net: stmmac: Set CIC bit only for TX queues with COE

Browse source

[ Upstream commit b1eded580a ]

Currently, in the AF_XDP transmit paths, the CIC bit of
TX Desc3 is set for all packets. Setting this bit for
packets transmitting through queues that don't support
checksum offloading causes the TX DMA to get stuck after
transmitting some packets. This patch ensures the CIC bit
of TX Desc3 is set only if the TX queue supports checksum
offloading.
