[0/7] add tx aggregation for mt7663s

Message

Lorenzo Bianconi Sept. 5, 2020, 9:26 a.m. UTC

Introduce sdio tx aggregation to reduce bus transaction ands improve tx
throughput. For the moment the skb are copied in a dedicated buffer
since mmc APIs do not support sg table for zero-copy.
Fixed a quota leak in mt7663s_refill_sched_quota.
Do not update quota in case of tx errors.
