[PATCH net-next 0/7][pull request] Intel Wired LAN Driver Updates 2023-08-01 (ice)

[Tony Nguyen]

This series contains updates to ice driver only.

Wojciech allows for LAG interfaces to be used for bridge offloads and
adds support for untagged VLAN traffic to be used in them as well.

Marcin tracks additional metadata for filtering rules to aid in proper
differentiation of similar rules. He also renames some flags that
do not entirely describe their representation.

Karol and Jan add additional waiting for firmware load on devices that
require it.

Przemek refactors RSS implementation to clarify/simplify configurations.

The following are changes since commit 01e6f8ad8d26ced14b0cf288c42e55d03a7c5070:
  net: dsa: qca8k: use dsa_for_each macro instead of for loop
and are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue 100GbE

Jan Sokolowski (1):
  ice: add FW load wait

Karol Kolacinski (1):
  ice: Add get C827 PHY index function

Marcin Szycik (2):

[PATCH net-next 1/7] ice: Accept LAG netdevs in bridge offloads

[Tony Nguyen]

From: Wojciech Drewek <wojciech.drewek@intel.com>

Allow LAG interfaces to be used in bridge offload using
netif_is_lag_master. In this case, search for ice netdev in
the list of LAG's lower devices.

[PATCH net-next 2/7] ice: Support untagged VLAN traffic in br offload

[Tony Nguyen]

From: Wojciech Drewek <wojciech.drewek@intel.com>

When driver receives SWITCHDEV_FDB_ADD_TO_DEVICE notification
with vid = 1, it means that we have to offload untagged traffic.
This is achieved by adding vlan metadata lookup.

Paul already asked about this behavior but it's unclear to me from the
answer whether this is a local custom or legit switchdev behavior.
Could someone with switchdev knowledge glance over this?

The only special vid is vid=0 (and that implies a VLAN-unaware FDB entry).
vid=1 is not special. Packets match on an FDB entry with vid=1 if they
are classified to VID 1 (obviously). That can happen if the bridge port
is VLAN-aware (bridge vlan_filtering=1) and:
- packet was untagged and pvid of the ingress port was 1, or
- packet was VLAN-tagged and the VID in the packet was 1
If the bridge has vlan_filtering=0, the rules are different, and packets
should only match FDB entries with vid=0. Both the (bridge) pvid of the
port and the VLAN header from the packet are to be ignored.

Thanks for clarification Vladimir, we will change our implementation.
Tony, you can drop this patch from the pull request.

[PATCH net-next 3/7] ice: Add direction metadata

[Tony Nguyen]

From: Marcin Szycik <marcin.szycik@linux.intel.com>

Currently it is possible to create a filter which breaks TX traffic, e.g.:

tc filter add dev $PF1 ingress protocol ip prio 1 flower ip_proto udp
dst_port $PORT action mirred egress redirect dev $VF1_PR

This adds a rule which might match both TX and RX traffic, and in TX path
the PF will actually receive the traffic, which breaks communication.

To fix this, add a match on direction metadata flag when adding a tc rule.

Because of the way metadata is currently handled, a duplicate lookup word
would appear if VLAN metadata is also added. The lookup would still work
correctly, but one word would be wasted. To prevent it, lookup 0 now always
contains all metadata. When any metadata needs to be added, it is added to
lookup 0 and lookup count is not incremented. This way, two flags residing
in the same word will take up one word, instead of two.

Note: the drop action is also affected, i.e. it will now only work in one
direction.

[PATCH net-next 4/7] ice: Rename enum ice_pkt_flags values

[Tony Nguyen]

From: Marcin Szycik <marcin.szycik@linux.intel.com>

enum ice_pkt_flags contains values such as ICE_PKT_FLAGS_VLAN and
ICE_PKT_FLAGS_TUNNEL, but actually the flags words which they refer to
contain a range of unrelated values - e.g. word 0 (ICE_PKT_FLAGS_VLAN)
contains fields such as from_network and ucast, which have nothing to do
with VLAN. Rename each enum value to ICE_PKT_FLAGS_MDID<number>, so it's
clear in which flags word does some value reside.

[PATCH net-next 5/7] ice: Add get C827 PHY index function

[Tony Nguyen]

From: Karol Kolacinski <karol.kolacinski@intel.com>

Add a function to find the C827 PHY node handle and return C827 PHY
index for the E810 products.

In order to bring this function to full functionality, some
helpers for this were written by Michal Michalik.

doesn't seem like this one needs to be declared in the header?

and this one is declared twice

[PATCH net-next 7/7] ice: clean up __ice_aq_get_set_rss_lut()

[Tony Nguyen]

From: Przemek Kitszel <przemyslaw.kitszel@intel.com>

Refactor __ice_aq_get_set_rss_lut() to improve reader experience and limit
misuse scenarios (undesired LUT size for given LUT type).

Allow only 3 RSS LUT type+size variants:
PF LUT sized 2048, GLOBAL LUT sized 512, and VSI LUT sized 64, which were
used on default flows prior to this commit.

Prior to the change, code was mixing the meaning of @params->lut_size and
@params->lut_type, flag assigning logic was cryptic, while long defines
made everything harder to follow.

Fix that by extracting some code out to separate helpers.
Drop some of "shift by 0" statements that originated from Intel's
internal HW documentation.

Drop some redundant VSI masks (since ice_is_vsi_valid() gives "valid" for
up to 0x300 VSIs).

After sweeping all the defines out of struct ice_aqc_get_set_rss_lut,
it fits into 7 lines.

Finally apply some cleanup to the callsite
(use of the new enums, tmp var for lengthy bit extraction).

Note that flags for 128 and 64 sized VSI LUT are the same,
and 64 is used everywhere in the code (updated to new enum here), it just
happened that there was 128 in flag name.

__ice_aq_get_set_rss_key() uses the same VSI valid bit, make constant
common for it and __ice_aq_get_set_rss_lut().
