From: Rohan G Thomas Date: Sat, 16 Sep 2023 06:33:11 +0000 (+0800) Subject: dt-bindings: net: snps,dwmac: Tx coe unsupported X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6fb8c20a04be234cf1cfd4bdd8cfb8860c9d2d3b;p=linux.git dt-bindings: net: snps,dwmac: Tx coe unsupported 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.
