d02342151c myri10ge: improve parity error detection and recovery
Improve myri10ge parity error detection and recovery:
1) Don't restore PCI config space to a rebooted NIC until AFTER the
   host is quiescent.
2) Let myri10ge_close() know the NIC is dead, so it won't waste time
   waiting for a dead nic to respond to MXGEFW_CMD_ETHERNET_DOWN
3) When the NIC is quiet (link down, or otherwise idle link) use
   a pci config space read to detect a rebooted NIC.  Otherwise
   we might never notice that a NIC rebooted

ec634fe328 net: convert remaining non-symbolic return values in ndo_start_xmit() functions
This patch converts the remaining occurences of raw return values to their
symbolic counterparts in ndo_start_xmit() functions that were missed by the
previous automatic conversion.

Additionally code that assumed the symbolic value of NETDEV_TX_OK to be zero
is changed to explicitly use NETDEV_TX_OK.

6ed106549d net: use NETDEV_TX_OK instead of 0 in ndo_start_xmit() functions
This patch is the result of an automatic spatch transformation to convert
all ndo_start_xmit() return values of 0 to NETDEV_TX_OK.

Some occurences are missed by the automatic conversion, those will be
handled in a seperate patch.

5b54814022 net: use symbolic values for ndo_start_xmit() return codes
Convert magic values 1 and -1 to NETDEV_TX_BUSY and NETDEV_TX_LOCKED respectively.

0 (NETDEV_TX_OK) is not changed to keep the noise down, except in very few cases
where its in direct proximity to one of the other values.

28679751a9 net: dont update dev->trans_start in 10GB drivers
Followup of commits 9d21493b4b
and 08baf56108
(net: tx scalability works : trans_start)
(net: txq_trans_update() helper)

Now that core network takes care of trans_start updates, dont do it
in drivers themselves, if possible. Multi queue drivers can
avoid one cache miss (on dev->trans_start) in their start_xmit()
handler.

Exceptions are NETIF_F_LLTX drivers (vxge & tehuti)

8c2f5fa51e myri10ge: fix stop/go ordering even more
The doorbell writes may be seen out of order by the firmware if they
are in WC memory since the tx spin(un)lock does not flush WC writes.
Hence if the "stop" is written on a different CPU than the "go", it
is possible that the stop will arrive after the go unless we add an
explicit memory barrier (and mmiowb() is not enough).

It fixes transmit hangs in multi tx queue mode.

The generic packet receive code takes care of setting

Some cases had to be skipped over because the drivers
