Commit Message

Yishai Hadas Dec. 23, 2018, 5:14 p.m. UTC 
From: Michael Guralnik <michaelgur@mellanox.com>

New port_cap_flags2 is derived from IB spec PortInfo CapabilityMask2.
The field is added to ibv_port_attr and a new flag in port_cap_flags for
port_cap_flags2 support is added.

In addition, a print of port_cap_flags2 was added to devinfo.
