A non-zero, non-descript value is needed as the hash key. The hash variable was left un-initialized; but sometimes it gets a zero value
and hashing is not effective. The constant value used now (not of any significance) seems to work fine.

Sending mbox cmds require multiple steps of writing to the DB register and polling
for an ack. Gettting interrupted in the middle by a signal breaks the mbox protocol.
Use msleep() to not get interrupted.

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
