cxgb4: Properly lock TX queue for the selftest.
[ Upstream commit 9067eccdd7849dd120d5495dbd5a686fa6ed2c1a ]
The selftest for the driver sends a dummy packet and checks if the
packet will be received properly as it should be. The regular TX path
and the selftest can use the same network queue so locking is required
and was missing in the selftest path. This was addressed in the commit
cited below.
Unfortunately locking the TX queue requires BH to be disabled which is
not the case in selftest path which is invoked in process context.
Lockdep should be complaining about this.
Use __netif_tx_lock_bh() for TX queue locking.

[ Upstream commit 9067eccdd7849dd120d5495dbd5a686fa6ed2c1a ]
The selftest for the driver sends a dummy packet and checks if the
packet will be received properly as it should be. The regular TX path
and the selftest can use the same network queue so locking is required
and was missing in the selftest path. This was addressed in the commit
cited below.
Unfortunately locking the TX queue requires BH to be disabled which is
not the case in selftest path which is invoked in process context.
Lockdep should be complaining about this.
Use __netif_tx_lock_bh() for TX queue locking.

All callers of tls_is_sk_tx_device_offloaded() currently do
an equivalent of:
if (skb->sk && tls_is_skb_tx_device_offloaded(skb->sk))
Have the helper accept skb and do the skb->sk check locally.
Two drivers have local static inlines with similar wrappers
already.
While at it change the ifdef condition to TLS_DEVICE.
Only TLS_DEVICE selects SOCK_VALIDATE_XMIT, so the two are
equivalent. This makes removing the duplicated IS_ENABLED()
check in funeth more obviously correct.

cxgb4: Use struct_group() for memcpy() region
In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally writing across neighboring fields.
Use struct_group() in struct fw_eth_tx_pkt_vm_wr around members ethmacdst,
ethmacsrc, ethtype, and vlantci, so they can be referenced together. This
will allow memcpy() and sizeof() to more easily reason about sizes,
improve readability, and avoid future warnings about writing beyond the
end of ethmacdst.
"pahole" shows no size nor member offset changes to struct
fw_eth_tx_pkt_vm_wr. "objdump -d" shows no object code changes.

The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below.
It has been hand modified to use 'dma_set_mask_and_coherent()' instead of
'pci_set_dma_mask()/pci_set_consistent_dma_mask()' when applicable.
This is less verbose.
It has been compile tested.

cxgb4: avoid link re-train during TC-MQPRIO configuration
When configuring TC-MQPRIO offload, only turn off netdev carrier and
don't bring physical link down in hardware. Otherwise, when the
physical link is brought up again after configuration, it gets
re-trained and stalls ongoing traffic.
Also, when firmware is no longer accessible or crashed, avoid sending
FLOWC and waiting for reply that will never come.
