* [PATCH] m68k/atari: EtherNEC - rewrite to use mainstream ne.c, take two

Here's take two of my patch to convert the m68k Atari ROM port Ethernet
driver to use mainstream ne.c, with minimal changes to the core NE2000
code.
In particular:
Changes to core net code:
* add a platform specific IRQ flag, so ne.c can share a hardware or
timer interrupt with some other interrupt source.
Changes to arch/m68k code:
* register the 8390 platform device on Atari only if the hardware is present
* retain the old driver (atari_ethernec.c in Geert's tree) under a
different config option, to be removed soon.
Regarding your suggestion that netpoll be used instead of a dedicated
timer interrupt: no changes to ne.c or 8390p.c are required to use
netpoll, it all works out of the box. All that is needed to use the
driver with netpoll is setting the device interrupt to some source that
can be registered, and enabling CONFIG_NETPOLL. Interrupt rate and hence
throughput is lower with netpoll though, which is why I still prefer the
dedicated timer option.
Comments?
Cheers,
Michael Schmitz

* [PATCH RESEND] net: lpc_eth: Fix rename of dev_hw_addr_random

* [PATCHv1] ipv6: Fix RTM_GETROUTE's interpretation of RTA_IIF to be consistent with ipv4
From: Shmulik Ladkani @ 2012-04-01 14:03 UTC (permalink / raw)
To: David S. Miller, netdev
Cc: linux-kernel, Eric Dumazet, Alexey Kuznetsov, James Morris,
Hideaki YOSHIFUJI, Patrick McHardy
In IPv4, if an RTA_IIF attribute is specified within an RTM_GETROUTE
message, then a route is searched as if a packet was received on the
specified 'iif' interface.
However in IPv6, RTA_IIF is not interpreted in the same way:
'inet6_rtm_getroute()' always calls 'ip6_route_output()', regardless the
RTA_IIF attribute.
As a result, in IPv6 there's no way to use RTM_GETROUTE in order to look
for a route as if a packet was received on a specific interface.
Fix 'inet6_rtm_getroute()' so that RTA_IIF is interpreted as "lookup a
route as if a packet was received on the specified interface", similar
to IPv4's 'inet_rtm_getroute()' interpretation.

Tested on v3.2.6. Patch applies to v3.3.
Few points to review:
1) An alternative: construction of an skb within 'inet6_rtm_getroute()'
and then calling 'ip6_route_input()' with the skb as an argument.
Thus, no need to split common code of 'ip6_route_input()'.
Less elegant IMO.
2) Better name for the new common function 'ip6_route_input_lookup()'
Will happily accept any better suggestions.
3) In IPv4 the 'ip_route_input()' call within 'inet_rtm_getroute()'is
protected by a 'local_bh_disable()' since dawn of history.
Not sure if similar protection needed within 'inet6_rtm_getroute()'.

* [PATCH] netfilter: don't do window scaling for a picked up connection
From: Changli Gao @ 2012-04-01 15:04 UTC (permalink / raw)
To: Pablo Neira Ayuso
Cc: Patrick McHardy, David S. Miller, netfilter-devel, netdev,
Changli Gao
For a picked up connection, the window scaling option is also lost, because this
option is only valid in SYN or SYN/ACK segments. We should remove the useless
expression to save the CPU power.

* [PATCH V2 net-next 00/28] ethtool: support time stamping and phc clocks
From: Richard Cochran @ 2012-04-01 15:19 UTC (permalink / raw)
To: netdev
Cc: e1000-devel, Martin Porter, John Ronciak, Ben Hutchings,
David Miller, Jacob Keller
Support for SO_TIMESTAMPING of network packets and PTP Hardware Clocks
has been expanding over the last year or two. In an ideal world, every
host would have exactly one PTP hardware clock, and every Ethernet MAC
would support SO_TIMESTAMPING on both the transmit and receive paths.
However, since we do not yet have full coverage for these features,
user space programs need a way to discover what a given interface
supports in these two areas.
* PTP Hardware Clocks
The relationship between the network interfaces and the (possibly
multiple) PHC devices is not discoverable except by knowing what
hardware you have got and carefully looking into the kernel log.
* SO_TIMESTAMPING
- Receive software time stamps are implemented in the stack
and thus work for all MAC hardware.
- Transmit software time stamps are only supported by a dozen
drivers or so.
- Some special devices support Tx/Rx time stamping in hardware.
- None of this is discoverable except by looking into the kernel
sources.
This series exposes the hardware and driver capabilities known to user
space via ethtool.
Since the PHC code was first merged, this has become the number one
requested new feature.
Patch number 3 applies on top of my recent two igb/phc patches.
Patch number 12 applies on top of my recent e100 patch.
The new feature has been tested on the following hardware:
igb Hardware time stamping in the MAC
dp83640 Hardware time stamping in the PHY
r8169 Software Tx time stamping in the MAC
Thanks,
Richard

In-Reply-To: <cover.1333289292.git.richardcochran@gmail.com>
This commit adds a new ethtool ioctl that exposes the SO_TIMESTAMPING
capabilities of a network interface. In addition, user space programs
can use this ioctl to discover the PTP Hardware Clock (PHC) device
associated with the interface.
Since software receive time stamps are handled by the stack, the generic
ethtool code can answer the query correctly in case the MAC or PHY
drivers lack special time stamping features.

* [PATCH V2 net-next 08/28] ethtool: Add a common function for drivers with transmit time stamping.
From: Richard Cochran @ 2012-04-01 15:19 UTC (permalink / raw)
To: netdev
Cc: e1000-devel, Martin Porter, John Ronciak, Ben Hutchings,
David Miller, Jacob Keller
In-Reply-To: <cover.1333289292.git.richardcochran@gmail.com>
Currently, most drivers do not support transmit SO_TIMESTAMPING. For those
that do support it, there is one appropriate response to the get_ts_info
query. This patch adds a common function providing this response.
