From b9c872f2316d27e2a323ffb410d706d680508093 Mon Sep 17 00:00:00 2001 From: Andy Gospodarek Date: Tue, 9 Jan 2018 16:06:16 -0500 Subject: [PATCH] net/mlx5e: Move generic functions to new file These functions were identified as ones that could be made generic and used by multiple drivers. Most of the contents of en_rx_am.c are moved to net_dim.c. Signed-off-by: Andy Gospodarek Acked-by: Tal Gilboa Acked-by: Saeed Mahameed Signed-off-by: David S.
