via-rhine: hardware VLAN support
This patch adds VLAN hardware support for Rhine chips.
The driver uses up to 3 additional bytes of buffer space when extracting
802.1Q headers; PKT_BUF_SZ should still be sufficient.
The initial code was provided by David Lv. I reworked it to use standard
kernel facilities. Coding style clean up mostly follows via-velocity.
Adapted to new interface for VLAN acceleration (per request of Jesse Gross).

While doing this analysis, I found a refcount bug in llc, I'll send a

Meanwhile, here is the patch for net-next-2.6
Your patch then can be applied after mine.

[PATCH] net: RCU conversion of dev_getbyhwaddr() and arp_ioctl()
dev_getbyhwaddr() was called under RTNL.
Rename it to dev_getbyhwaddr_rcu() and change all its caller to now use
RCU locking instead of RTNL.
Change arp_ioctl() to use RCU instead of RTNL locking.

can: add slcan driver for serial/USB-serial CAN adapters
This patch adds support for serial/USB-serial CAN adapters implementing the
LAWICEL ASCII protocol for CAN frame transport over serial lines.
The driver implements the SLCAN line discipline and is heavily based on the

This patch adds a generic infrastructure for policy-based dequeueing of
TX packets and provides two policies:
* a simple FIFO policy (which is the default) and
* a priority based policy (set via socket options).
Both policies honour the tx_qlen sysctl for the maximum size of the write
queue (can be overridden via socket options).
The priority policy uses skb->priority internally to assign an u32 priority
identifier, using the same ranking as SO_PRIORITY. The skb->priority field
is set to 0 when the packet leaves DCCP. The priority is supplied as ancillary
data using cmsg(3), the patch also provides the requisite parsing routines.

The mcfw *never* sends CMDDONE when rebooting. Changing this so that it always
sends CMDDONE *before* REBOOT is easy on Siena, but it's not obvious that we
could guarantee to be able to implement this on future hardware.
Given this, I'm less convinced that the protocol should be changed.
To reiterate the failure mode: The driver sees this:
issue command
receive REBOOT event
Was that reboot event sent before the command was issued, or in
response to the command? If the former then there will be a subsequent
CMDDONE event, if the latter, then there will be no CMDDONE event.
Options to resolve this are:
1. REBOOT always completes an outstanding mcdi request, and we set
the credits count to ignore a subsequent CMDDONE event with
mismatching seqno.
2. REBOOT never completes an outstanding mcdi request. If there is
no CMDDONE event then we rely on the mcdi timeout code to complete
the outstanding request, incurring a 10s delay.
I'd argue that (2) is tidier, but that incurring a 10s delay is a little
needless. Let's go with (1).

tipc: Delete useless function prototypes
Removes several function declarations that aren't used anywhere,
either because they reference routines that no longer exist or
because all users of the function reference it after it has already
been defined.

tipc: Remove obsolete native API files and exports
As part of the removal of TIPC's native API support it is no longer
necessary for TIPC to export symbols for routines that can be called
by kernel-based applications, nor for it to have header files that
kernel-based applications can include to access the declarations for
those routines. This commit eliminates the exporting of symbols by
TIPC and migrates the contents of each obsolete native API include
file into its corresponding non-native API equivalent.
The code which was migrated in this commit was migrated intact, in
that there are no technical changes combined with the relocation.

tcp: Add timewait recycling bits to ipv6 connect code.
This will also improve handling of ipv6 tcp socket request
backlog when syncookies are not enabled. When backlog
becomes very deep, last quarter of backlog is limited to
validated destinations. Previously only ipv4 implemented
this logic, but now ipv6 does too.
Now we are only one step away from enabling timewait
recycling for ipv6, and that step is simply filling in
the implementation of tcp_v6_get_peer() and
tcp_v6_tw_get_peer().

bnx2x: Add Nic partitioning mode (57712 devices)
NIC partitioning is another flavor of multi function - having few
PCI functions share the same physical port. Unlike the currently
supported mode of multi-function which depends on the switch
configuration and uses outer-VLAN, the NPAR mode is switch independent
and uses the MAC addresses to distribute incoming packets to the different
functions. This patch adds the specific HW setting of the NPAR mode
and some distinctions between switch dependent (SD) and
switch independent (SI) multi-function (MF) modes where the configuration
is not the same.

inet: Turn ->remember_stamp into ->get_peer in connection AF ops.
Then we can make a completely generic tcp_remember_stamp()
that uses ->get_peer() as a helper, minimizing the AF specific
code and minimizing the eventual code duplication when we implement
the ipv6 side of TW recycling.
