From 6ed0e08f9e2a90ab455d897e4679b903c82dac67 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Tue, 17 Apr 2018 23:36:12 +0200 Subject: [PATCH] r8169: remove jumbo_tx_csum from chip config struct According to the chip configuration entries only RTL8169 (ver <= 06) supports tx checksumming for jumbo packets. By the way: constant JUMBO_1K is a little misleading because it refers to the standard packet size and not to a jumbo packet size. By implementing this rule we can get rid of configuring tx checksumming support per chip type. Signed-off-by: Heiner Kallweit Signed-off-by: David S.
