Hi,

This series improves channel creation time by moving per-channel MKEY
initialization from a slow-path FW command to a fast-path UMR WQE.

The benefit becomes more significant with larger MKEYs and a higher
number of channels.

On my setup with the maximum configuration (248 channels, MTU 9000,
RX/TX ring size 8K), the "interface up" operation is 2.081 seconds
faster:

Before: 5.618 seconds
After:  3.537 seconds

This corresponds to ~8.4 msec saved per channel.

Regards,
Tariq

Thanks,
