With RX coalescing, one CQE entry can be used to indicate multiple packets
on the receive queue. This saves processing time and PCI bandwidth over
the CQ.

Why didn't you change mana_cfg_vport_steering() too?

The mana_cfg_vport_steering() is for mana_en (Enthernet) driver, not the
mana_ib driver.

The changes for mana_en will be done in a separate patch together with
changes for mana_en RX code patch to support multiple packets / CQE.

Thanks,
