From: Jose Abreu Date: Wed, 6 Nov 2019 15:03:04 +0000 (+0100) Subject: net: stmmac: Fix TSO descriptor with Enhanced Addressing X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=b2f071995b7a4f175467d683d4d18eab10810020;p=uclinux-h8%2Flinux.git net: stmmac: Fix TSO descriptor with Enhanced Addressing When using addressing > 32 bits the TSO first descriptor only has the header so we can't set the payload field for this descriptor. Let's reset the variable so that buffer 2 value is zero. Fixes: a993db88d17d ("net: stmmac: Enable support for > 32 Bits addressing in XGMAC") Signed-off-by: Jose Abreu Signed-off-by: David S.
