tg3: Relax 5717 serdes restriction
tg3 is coded to refuse to attach to 5717 serdes devices. Now that the
hardware is better supported, we can relax this restriction. This patch
also fixes a recently introduced bug which will cause serdes parallel
detection not to work with 5780 class devices.

tg3: Fix single MSI-X vector coalescing
The interrupt coalescing setup code used the TG3_FLG2_USING_MSIX flag to
determine whether or not to configure the rx coalescing parameters.
This is incorrect for the single MSI-X vector case. This patch changes
the code to look at the TG3_FLG3_ENABLE_RSS instead.

If dev_alloc_skb() failed then free already allocated skbs.
remove_rx_bufs() can be called multiple times, so set rbd->skb to NULL
to avoid double free. remove_rx_bufs() was moved upwards to be seen by
init_rx_bufs().

net: Get rid of rtnl_link_stats64 / net_device_stats union
In commit be1f3c2c027cc5ad735df6a45a542ed1db7ec48b "net: Enable 64-bit
net device statistics on 32-bit architectures" I redefined struct
net_device_stats so that it could be used in a union with struct
rtnl_link_stats64, avoiding the need for explicit copying or
conversion between the two. However, this is unsafe because there is
no locking required and no lock consistently held around calls to
dev_get_stats() and use of the statistics structure it returns.
In commit 28172739f0a276eb8d6ca917b3974c2edb036da3 "net: fix 64 bit
counters on 32 bit arches" Eric Dumazet dealt with that problem by
requiring callers of dev_get_stats() to provide storage for the
result. This means that the net_device::stats64 field and the padding
in struct net_device_stats are now redundant, so remove them.
Update the comment on net_device_ops::ndo_get_stats64 to reflect its
new usage.
Change dev_txq_stats_fold() to use struct rtnl_link_stats64, since
that is what all its callers are really using and it is no longer
going to be compatible with struct net_device_stats.
Eric Dumazet suggested the separate function for the structure
conversion.

iwlagn: fix the bit mask of a FH register in stop Tx DMA flow
When we stop the Tx DMA channels, we poll bits 16:31 in
FH_TSSR_RX_STATUS_REG. From 4965 and up, only the bits 16:26 are legal.
Bits 27:31 are not used and are always unset.
Polling them will lead to fail on timeout but since the timeout is quite
small, the stall was not felt.

ucode errors were redefined in new ucode images and all new errors

are not sequential so additional lookup table added. errors do not
