Saeed Mahameed 6982ab6097 net/mlx5e: Xmit, no write combining ... mlx5e netdev Blue Flame (write combining) support demands a lot of overhead for a little latency gain for some special cases, this overhead is hurting the common case. Here we remove xmit Blue Flame support by creating all bfregs with no write combining for all SQs, and we remove a lot of BF logic and conditions from xmit data path. Simplify mlx5e_tx_notify_hw (doorbell function) by removing BF related code and by removing one memory barrier needed for WC mapped SQ doorbell buffers, which no longer exist.
