Check if CTS bit is set in the mailbox message before waiting for ACK.
Otherwise ACK will never be received causing the function to timeout. Add
a note for ixgbe_write_mbx that it should be called while holding a lock.

Add tso_tcp_flags_mask_first_segment, tso_tcp_flags_mask_middle_segment, and tso_tcp_flags_mask_last_segment sysctl-variables to control the handling of TCP flags during TSO. This allows to fix the masks appropriate for classical ECN and to configure appropriate masks for accurate ECN. Michael notes emperically 82599 has an unexpected middle mask: Chip First Middle Last 82599 0xFF6 0xFF6 0xF7F which should be fixed up to 0xF76 (RFC 3168) in a future commit.

This is a relatively well known trick for the X520 (82599), can be useful for testing and lab settings. It's not an official standard or particularly common but ubiquitous Broadcom switch ASICs deal with it. We'll call it 1000Base-KX because it's SerDes on the passive cable and I don't think it's worth adding another media type for this.

In the QEMU workaround code in if_ixv.c, the ixv driver calls pci_find_cap(dev, PCIY_MSIX, &rid). It is not checking the return code from that function and the function appears to always be failing. This then causes the driver to use the rid variable uninitialized, which will mean setting a bit at an arbitrary offset in pci config space. For now, this seems to have no adverse impact, but it could easily cause very subtle problems. PR: 207037 Sponsored by: BBOX.io (cherry picked from commit b87b3696c973ef0a9df70143cd89f6b488531e93)
