From 364366f5bbd95d0a62c9ec79a5b80aae21266ba3 Mon Sep 17 00:00:00 2001 From: Rohan G Thomas Date: Sat, 16 Sep 2023 14:33:11 +0800 Subject: [PATCH] dt-bindings: net: snps,dwmac: Tx coe unsupported commit 6fb8c20a04be234cf1cfd4bdd8cfb8860c9d2d3b upstream. Add dt-bindings for coe-unsupported property per tx queue. Some DWMAC IPs support tx checksum offloading(coe) only for a few tx queues. DW xGMAC IP can be synthesized such that it can support tx coe only for a few initial tx queues. Also as Serge pointed out, for the DW QoS IP tx coe can be individually configured for each tx queue. This property is added to have sw fallback for checksum calculation if a tx queue doesn't support tx coe. Signed-off-by: Rohan G Thomas Acked-by: Conor Dooley Signed-off-by: David S.
