3c60e22da7 cxgbe(4): Add support for Chelsio's Terminator 5 (aka T5) ASIC. This 
includes support for the NIC and TOE features of the 40G, 10G, and
1G/100M cards based on the T5.

The ASIC is mostly backward compatible with the Terminator 4 so cxgbe(4)
has been updated instead of writing a brand new driver.  T5 cards will
show up as cxl (short for cxlgb) ports attached to the t5nex bus driver.

being introduced here.

This should fix kern/173584 too.  Setting hw.cxgbe.fw_install=2 will
mostly do what was requested in the PR but it's a bit more intelligent
in that it won't reinstall the same firmware repeatedly if the knob is
left set.

where do_pass_establish on another CPU (the driver chose a different
queue for the new tid) expands the synq entry into a full PCB and then
releases the only hold on it, all while do_pass_accept_req is still
running.

14a5904236 cxgbe/tom: Basic CLIP table management. 
This is the Compressed Local IPv6 table on the chip.  To save space, the
chip uses an index into this table instead of a full IPv6 address in
some of its hardware data structures.

For now the driver fills this table with all the local IPv6 addresses
that it sees at the time the table is initialized.  I'll improve this
later so that the table is updated whenever new IPv6 addresses are
configured or existing ones deleted.
