Subject: [RESEND PATCH net-next 1/1] ice: Simplify tracking status of RDMA support
From: Dave Ertman <david.m.ertman@...el.com>
The status of support for RDMA is currently being tracked with two
separate status flags. This is unnecessary with the current state of
the driver.
Simplify status tracking down to a single flag.
Rename the helper function to denote the RDMA specific status and
universally use the helper function to test the status bit.
