Message-ID: <165063955516.27138.14461751045463833784.stgit@palantir17.mph.net>
Date: Fri, 22 Apr 2022 15:59:15 +0100
From: Martin Habets <habetsm.xilinx@...il.com>
To: kuba@...nel.org, pabeni@...hat.com, davem@...emloft.net
Cc: netdev@...r.kernel.org, ecree.xilinx@...il.com
Subject: [PATCH net-next 10/28] sfc/siena: Rename functions in rx_common.h
to avoid conflicts with sfc
From: Martin Habets <martinh@...inx.com>
For siena use efx_siena_ as the function prefix.
Several functions are not used in Siena, so they are removed.
Signed-off-by: Martin Habets <habetsm.xilinx@...il.com>
