Hi, DW xGMAC IP can be synthesized such that it can support tx checksum offloading 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 patchset adds support for tx coe sw fallback for those queues that don't support tx coe. Also, add binding for snps,coe-unsupported property. changelog v6: * Reworked patchset to cover DW QoS Ethernet IP also. changelog v5: * As rightly suggested by Serge, reworked redundant code. changelog v4: * Replaced tx_q_coe_lmt with bit flag. changelog v3: * Resend with complete email list. changelog v2: * Reformed binding description. * Minor grammatical corrections in comments and commit messages.
