To support host systems with non 4K page size, l2_db_size shall be
calculated with 4096 instead of PAGE_SIZE. Also, supply the host page size
to FW during initialization.

Broadcom's adapter supports more granular statistics
to allow better understanding about the state of the
chip when data traffic is flowing.
Exposing the detailed stats to the consumer through
the standard hook available in the kverbs interface.
In order to retrieve all the information, driver
implements a firmware command.

Depending on the OS page-table configurations, applications
may request MRs which has page size alignment other than 4K
Underlying provider driver needs to adjust its PBL boundaries
according to the incoming page boundaries in the PA list.
Adding a capability to register MRs having pages-sizes other
than 4K (Hugepages).

RoCE can be used by virtual functions (VFs) as well. Adding
code changes to allow resource reservation, initialization
and avail the resources to the RDMA applications running on
those VFs.
Currently, fifty percent of the total available resources
are reserved for PF and remaining are equally divided among
active VFs.

Current implementation does not program vlan header insertion
in RoCE packet if no vlan is configured. Firmware does not add
prority when there is no vlan tag in the packet. Modify the code
to insert vlan header when PFC is enabled on the interface.

This patch introduces the RoCE driver for the Broadcom
NetXtreme-E 10/25/40/50G RoCE HCAs.
The RoCE driver is a two part driver that relies on the parent
bnxt_en NIC driver to operate. The changes needed in the bnxt_en
driver have already been incorporated via Dave Miller's net tree
into the mainline kernel.
The vendor official git repository for this driver is available
on github as:
