Subject: [PATCH v2 3/9] RDMA/rxe: Fixup rxe_send and rxe_loopback
Date: Tue,  6 Jul 2021 23:00:35 -0500	[thread overview]
Message-ID: <20210707040040.15434-4-rpearsonhpe@gmail.com> (raw)
In-Reply-To: <20210707040040.15434-1-rpearsonhpe@gmail.com>

Fixup rxe_send() and rxe_loopback() in rxe_net.c to have the same
calling sequence. This patch makes them static and have the same
parameter list and return value.
