[PATCH 00/29] make the driver ready for multi-vif support

[PATCH 00/29] make the driver ready for multi-vif support

[Eliad Peller]

This patchset finishes adding multiple vif support to the
wl12xx driver.

The driver still allows only a single vif, as the current
fw only supports a single vif.

This patchset doesn't break compatibility with the current fw.

Eliad Peller (29):
  wl12xx: refactor fw init into a new function
  wl12xx: move last_tx_hlid into wlvif
  wl12xx: unify STA and AP tx_queue mechanism
  wl12xx: move some functions from remove_interface() to stop()
  wl12xx: move bitrate_masks into wlvif
  wl12xx: add vifs list
  wl12xx: support multiple vifs in the tx path
  wl12xx: configure sleep_policy according to active roles
  wl12xx: make event handling support multirole
  wl12xx: move tx_security_seq into wlvif
  wl12xx: rearm rx streaming per vif
  wl12xx: make WL1271_FLAG_STA_ASSOCIATED flag per-vif
  wl12xx: make WL1271_FLAG_IBSS_JOINED flag per-vif
  wl12xx: make WL1271_FLAG_AP_STARTED flag per-vif
  wl12xx: make WL1271_FLAG_PSM flag per-vif
  wl12xx: make WL1271_FLAG_STA_STATE_SENT flag per-vif
  wl12xx: make WL1271_FLAG_RX_STREAMING_STARTED flag per-vif
  wl12xx: make WL1271_FLAG_IF_INITIALIZED per-vif
  wl12xx: make WL1271_FLAG_PSPOLL_FAILURE flag per-vif
  wl12xx: make WL1271_FLAG_CS_PROGRESS flag per-vif
  wl12xx: add band field to wlvif
  wl12xx: add channel field to wlvif
  wl12xx: add power_level field to wlvif
  wl12xx: make op_config configure all vifs
  wl12xx: replace all remaining wl->vif references
  wl12xx: call stop() on recovery
  wl12xx: use dynamic rate policies
  wl12xx: add elp wakeup/sleep calls to add_interface
  wl12xx: use round-robin policy for tx

[PATCH 01/29] wl12xx: refactor fw init into a new function

[Eliad Peller]

The fw boot and initialization currently happens inside the
add_interface() callback. This is wrong, as add_interface is
called for each new vif. However, we due to some fw limitation
(we have to know the actual mac address on boot), we can't
completely move it into the start() callback.

Until the fw will be fixed, refactor the fw init into
a new function, and call it from add_interface()

No big deal at this point, so I'll apply this, but maybe we should print
the last_tx_hlid from inside all the vifs as well?

i plan to add a new vif_state debugfs key that will print all the relevant info.

[PATCH 03/29] wl12xx: unify STA and AP tx_queue mechanism

[Eliad Peller]

Make sta use the global wl->links[hlid].tx_queue (by
considering its links map) instead of wl->tx_queue,
and then unify the tx and tx_reset flows for the
various vifs.

[PATCH 06/29] wl12xx: add vifs list

[Eliad Peller]

keep a list of all the vifs associated with our hw.
it will be later used in order to iterate through vifs.

I know we alredy call this kind of thing "list" struct wl1271 for the
ARP stuff, but I prefer "node" so it's easier to follow when calling
list_add and friends.  Mind changing?

This looks fine, but is it really necessary? I think the call to
list_for_each_entry is clear enough already, isn't it?

i think "list" is the standard convention (e.g. see sta_info,

i find it easier to understand this way.
also, future patches will add wl12xx_for_each_wlvif_sta and
wl12xx_for_each_wlvif_ap, so it even makes more sense to use this
macro.

Yeah, it makes a bit of sense, because each node is actually a head of a
list.  Still, I don't like it because it's annoying to read it a
list_add() with two lists.  It's not intuitive to know which one is
which.  Anyway, it's fine to leave it like this.

Yeah, I now saw the other macros and it now makes a bit more sense for
the other ones.  But I dislike simple macros whose content are almost as
easy to understand as the macro name, because one needs to go dig the
macro out to figure out exactly what it is doing.  With no macro, it
would be much easier to figure out that this is a simple
list_for_each_entry(), because you would simply call that explicitly. ;)
It's as annoying as unnecessary typedefs.

But I'm in a temporary and unusual mood of accepting stuff easier than
usual right now, so it's fine to keep it like this. ;)

What's wrong with ieee80211_iterate_active_interfaces() :-)

defining iterator for each time we want to iterate is pretty cumbersome :)

[PATCH 07/29] wl12xx: support multiple vifs in the tx path

[Eliad Peller]

Pass the wlvif associated with each skb as param.

Note that dummy packet doesn't belong to any
particular vif, so we pass NULL in this case.

[PATCH 08/29] wl12xx: configure sleep_policy according to active roles

[Eliad Peller]

If there is an active AP role, stay always on.
Otherwise, allow chip to enter elp.

(Note that this is a global configuration, so if the
device is already configured according to our policy,
we don't have to configure it again)

Wouldn't it be much simpler to have a "have_ap" element in the wl
struct?

have_ap is not enough, because there might be multiple aps, and we
need to consider it on removal.
we can use ap_count, if you prefer it that way.

[PATCH 09/29] wl12xx: make event handling support multirole

[Eliad Peller]

Some events don't indicate the role they are intended for.
In these cases, iterate through all the relevant vifs,
and pass the event to each one of them.

This is only a workaround. future fw releases should indicate
the relevant role_id for such events.

Is this workaround really necessary? Are we going to have a firmware
that supports multi-role but does *not* pass the role_id for these
events?

i hope not. :)
but in the meantime, we use this workaround to keep compatibility with
the current (single-role) fw.

What I meant is that you could keep this global, without moving it
temporarily to the wlvif and traversing the list, which has always only
a single element anyway.  But now I see that you want to get rid of the
global wl->vif, so it's fine.  It's only the list traversal that is
actually a workaround, the rest of the changes are actually fine.

[PATCH 10/29] wl12xx: move tx_security_seq into wlvif

[Eliad Peller]

The last security seq num has to be saved across reconfigs.
Add a new "persistent" struct into wlvif, which won't get
deleted on wl12xx_init_vif_data()

...because we're accessing it directly here?

And don't we get TX complete events for dummy packets?

We could change this (... + 256) % 256 here for & 0xFF as Ido suggested

[PATCH 11/29] wl12xx: rearm rx streaming per vif

[Eliad Peller]

Currently, the rx streaming doesn't support multi-vif
(the actual wlvif is taken from wl->vif, and the management
is global).

Make the rx streaming timers/works per-vif, and pass the
the actual vif as param.

[PATCH 21/29] wl12xx: add band field to wlvif

[Eliad Peller]

add band field into the per-interface data.

mac80211 configures some values (e.g. band, channel)
globally, while we configure them per-interface.

In order to make it easier to keep track of the
configured value for each value while keeping sync
with mac80211, save these values both globally
and per-vif.

Seems like wl12xx_roc(), which is the only caller of wl12xx_cmd_roc(),
is always called with wlvif->role_id as the role, so it seems a bit
useless to pass role_id separately all the way.

in fact, it's usually being called with wlvif->dev_role_id, so we do
need this param.

(otoh, wl12xx_roc is usually get called along with start_role_dev. i
have some pending patch that couples them together and cleans the code
a bit. i'll send it soon).

Guys,

Just fyi we will use the roc/croc also in DFS implementation.

Thanks,
Victor.

[PATCH 22/29] wl12xx: add channel field to wlvif

[Eliad Peller]

add channel into the per-interface data.

mac80211 configures some values (e.g. band, channel)
globally, while we configure them per-interface.

In order to make it easier to keep track of the
configured value for each value while keeping sync
with mac80211, save these values both globally
and per-vif.

[PATCH 23/29] wl12xx: add power_level field to wlvif

[Eliad Peller]

move power_level into the per-interface data.

mac80211 configures some values (e.g. band, channel)
globally, while we configure them per-interface.

In order to make it easier to keep track of the
configured value for each value while keeping sync
with mac80211, save these values both globally
and per-vif.

[PATCH 25/29] wl12xx: replace all remaining wl->vif references

[Eliad Peller]

wl->vif is appropriate only when a single vif is being used.
Instead, pass wlvif as parameter or iterate through all
the vifs (e.g. when a global configuration was changed)

Leave wl->vif only to determine whether a vif was already
added (this check will be removed as well after both the
driver and fw will support multiple vifs)

* used '(foo - bar) & 0xff' instead of '(foo - bar + 256) % 256'.
