be2net: adding support for Lancer family of CNAs
Key changes are:
- EQ ids are not assigned consecutively in Lancer. So, fix mapping of MSIx
vector to EQ-id.
- BAR mapping and some req locations different for Lancer.
- TCP,UDP,IP checksum fields must be compulsorily set in TX wrb for TSO in
Lancer.
- CEV_IST reg not present in Lancer; so, peek into event queue to check for
new entries
- cq_create and mcc_create cmd interface is different for Lancer; handle
accordingly
