Several of the Intel ethernet drivers keep an atomic counter used to
manage when to actually hit the hardware with a disable or an enable.
The way the net_rx_work() breakout logic works during a pending
napi_disable() is that it simply unschedules the poll even if it
still has work.
This can potentially leave interrupts disabled, but that is OK
because all of the drivers are about to disable interrupts
anyways in all such code paths that do a napi_disable().
Unfortunately, this trips up the semaphore used here in the Intel
drivers. If you hit this case, when you try to bring the interface
back up it won't enable interrupts. A reload of the driver module
fixes it of course.
So what we do is make sure all the sequences now go:
napi_disable();
atomic_set(&adapter->irq_sem, 0);
*_irq_disable();
which makes sure the counter is always in the correct state.

wn3_config is shared by these cards; the way we deal with it is both bad C
(union abuse) and broken on big-endian. For 3c515 it's less serious (ISA
cards are quite rare outside of little-endian boxen), but 3c574 is a pcmcia
one and that'd better be endian-independent... Fix is the same in both
cases.

The driver sets up the hardware to accept a frame with max length
equal to MTU + Ethernet header + FCS + VLAN tag, but we neglect to
add the VLAN tag size to the ingress buffer. When a VLAN-tagged
frame arrives, the hardware passes it, but bad things happen
because the buffer is too small. This patch fixes that.
Thanks to David Harris for reporting the bug and testing the fix.

Fix the handling of rtnl and the bonding_rwsem to always be acquired

in the opposite order, which opens a window for deadlock between ifenslave

Fix the functions that store the primary and active slave
options via sysfs to hold the correct locks in the correct order.
The bond_change_active_slave and bond_select_active_slave
functions both require rtnl, bond->lock for read and curr_slave_lock for
write_bh, and no other locks. This is so that the lower level
mode-specific functions (notably for balance-alb mode) can release locks
down to just rtnl in order to call, e.g., dev_set_mac_address with the
locks it expects (rtnl only).

The Tx skb release could not free more than one skb per call.
Add it to the fact that the xmit handler does not check for
a queue full condition and you have a recipe to leak quickly.
Let's release every pending Tx descriptor which has been given
back to the host CPU by the network controller. The xmit handler
suggests that it is done through the IPG_TFC_TFDDONE bit.
Remove the former "curr" computing: it does not produce anything
usable in its current form.

As pointed out by Jesse Brandeburg, for three of the drivers edited

running TX reclaim forever. If this occurs, we have to elide NAPI
poll completion or else those TX events will never be serviced.

As Johannes Berg indicated, the NET_IP_ALIGN doesn't
need to be used for ieee80211 frames. This means we
can simplify the alignment calculation to just
use the result of the header size modulus 4 as frame
alignment.
Furthermore we shouldn't use NET_IP_ALIGN in rt2x00usb
because it could be 0 on some architectures and we absolutely
need to have 2 bytes reserved for possible aligning.

it reports a that WOL is disabled when it isn't.

This cleans up some unnecessary byte-swapping while setting up tx and
