Subject: RDMA/rxe: remove rxe_ib_device_get_netdev() and RXE_PORT
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=dd677609753c847a433cfbc90a6ce9c18281e6a3;p=thirdparty%2Fkernel%2Flinux.git

RDMA/rxe: remove rxe_ib_device_get_netdev() and RXE_PORT

Suggested by Leon, remove the rxe_ib_device_get_netdev() wrapper and
the RXE_PORT definition. These additions do not improve readability,
and RXE has always had only a single port.
