Subject: [PATCH] rdma: Fix representation of PortInfo CapabilityMask
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1664694
Upstream Status: iproute2.git commit d090fbf33bd15
commit d090fbf33bd15d82978596920b07616aa119ac2f
Author: Leon Romanovsky <leonro@mellanox.com>

rdma: Fix representation of PortInfo CapabilityMask
The port capability mask represents IBTA PortInfo specification,
but as it is written in description of kernel commit 2f944c0fbf58
("RDMA: Fix storage of PortInfo CapabilityMask in the kernel"),
the bit 26 was mistakenly overwritten.
The rdmatool followed it too and mislead users by presenting wrong
value. Since it never showed proper value, we update the whole
port_cap_mask to comply with IBTA and show real HW values.
Fixes: da990ab40a92 ("rdma: Add link object")
