When forcedeth module is unloaded, there exists a path that can lead
to mod_timer() after del_timer_sync(), causing an oops. This patch
short-circuits this unneeded path, which originates in
nv_get_ethtool_stats().

Tested:
  x86_64 16-way + 3 ethtool -S infinite loops + 100Mbps incoming traffic
  + rmmod/modprobe/ifconfig in a loop

Changes to support other Optima types, introduced an accidental
regression that caused 88E8059 to come up in 10Mbit/sec.

The Yukon Optima supports a reverse auto-negotiation feature that
was incorrectly setup, and not needed. The feature could be used to
allow wake-on-lan at higher speeds. But doing it correctly would require
other changes to initialization.

L2TP for example uses NLA_MSECS like this:
policy:
        [L2TP_ATTR_RECV_TIMEOUT]        = { .type = NLA_MSECS, },
code:
        if (info->attrs[L2TP_ATTR_RECV_TIMEOUT])
                cfg.reorder_timeout = nla_get_msecs(info->attrs[L2TP_ATTR_RECV_TIMEOUT]);

As nla_get_msecs() is essentially nla_get_u64() plus the
conversion to a HZ-based value, this will not properly
reject attributes from userspace that aren't long enough
and might overrun the message.

Add NLA_MSECS to the attribute minlen array to check the
size properly.

i825xx and xscale are "sub" Kconfigs to NET_VENDOR_INTEL, so
NET_VENDOR_INTEL should contain ALL the dependencies of the
"sub" Kconfigs.

Same with 8390 is a "sub" Kconfig to NET_VENDOR_NATSEMI, so
NET_VENDOR_NATSEMI needs to contains ALL the dependencies.

Freescale Kconfig only had fs_enet as a sub Kconfig, and already
contained the needed dependencies, just cleaned up the dependencies.

When implementing VRRP v2 using macvlan several problems were
discovered.  VRRP is weird in that all routers participating
in a redundant group use the same virtual MAC address.
Macvlan is a natural driver to use for this but it doesn't
work.  The problem is that packets with a macvlan device's
source address are not received.

The problem is actually a regression that date back almost 2 years now.
The original problems started with:

commit 618e1b74
Author: Arnd Bergmann <arnd@arndb.de>
Date:   Thu Nov 26 06:07:10 2009 +0000

    macvlan: implement bridge, VEPA and private mode

This patches restores the original 2.6.32 behavior. Allowing multicast
packets received with the VRRP source address to be received.

During shutdown, it is impossible to reliably disable the timer and
reset_task threads.  Each thread can schedule the other, which leads to
shutdown code that chases its tail.

To fix the problem, this patch removes the ability of tg3_reset_task to
schedule a new timer thread.  To support this change, tg3_timer no
longer terminates itself, but rather goes into a polling mode.

It is possible for multiple threads in the tg3 driver to each attempt to
schedule a run of tg3_reset_task().  The multiple tg3_reset_task
executions could all wind up on the same queue (and execute serially) or
wind up on the queues of another processor (which could execute in
parallel).  Either scenario is not what was truly desired.

This patch adds a new flag, TG3_FLAG_RESET_TASK_PENDING, and uses it to
determine whether or not to schedule another run of tg3_reset_task().
With the new flag comes two new functions to facilitate scheduling and
descheduling of tg3_reset_task().

The new 4k tx bd segmentation code had a bug in the error cleanup path.
If the driver did not map all the physical fragments, the abort path
would wind up advancing the producer index beyond the point where the
setup code stopped.  This would ultimately turn into a tx recovery error
where the driver would expect the skb pointer to be set when it isn't.
This patch fixes the problem, and then makes the code a little easier to
understand.

APE mutex register blocks are shared by all ports of multiport devices.
For some mutexing purposes, each function is assigned their own
register.  For other cases, each function is assigned its own request
and grant bits of a single register.  For the latter cases, the tg3
driver is incorrectly allowing each function to use the same set of
grant / request bits.  This patch fixes the code so that each function
uses the appropriate bitset.

The RC error state flush logic in qib_make_rc_req() could return all
of the acked wqes and potentially have emptied the queue.  It would
then unconditionally try return a flush completion via
qib_send_complete() for an invalid wqe, or worse a valid one that is
not queued. The panic results when the completion code tries to
maintain an MR reference count for a NULL MR.

This fix modifies logic to only send one completion per
qib_make_rc_req() call and changing the completion status from
IB_WC_SUCCESS to IB_WC_WR_FLUSH_ERR as the completions progress.

The outer loop will call as many times as necessary to flush the queue.
