Zerocopy can coalesce notifications of up to 65535 send calls.
Excessive coalescing increases notification latency and process

In the simple case, each sendmsg() call generates data and eventually
a zerocopy ready notification N, where N indicates the Nth successful
invocation of sendmsg() with the MSG_ZEROCOPY flag on this socket.

Refine skb_copy_ubufs to support compount pages. With upcoming TCP

These skbuffs can have both kernel and zerocopy fragments, e.g., when

reference.

Add sock_omalloc and sock_ofree to be able to allocate control skbs,

In the VF driver, module parameter mlx4_log_num_mgm_entry_size was
mistakenly overwritten -- and in a manner which overrode the
device-managed flow steering option encoded in the parameter.
log_num_mgm_entry_size is a global module parameter which

Currently vport representors are added only on driver load and removed on

When the admin enables/disables cqe compression, updating
mpwqe stride size is required:
CQE compress ON ==> stride size = 256B
CQE compress OFF ==> stride size = 64B
This is already done on driver load via mlx5e_set_rq_type_params, all we
