This patchset adds support for tx coe sw fallback for those queues that don't support tx coe. Also, add binding for snps,tx-queues-with-coe property. 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.
