This patch introduces the RoCE driver for the
Broadcom NetXtreme-E 10/25/50/100/200G RoCE HCAs.
The RoCE driver is a two part driver that relies
on the bnxt_en NIC driver to operate. The changes
needed in the bnxt_en driver is included through
another patch "L2-RoCE driver communication interface"
in this set.
Presently, There is no user space support, Hence
recommendation to use the krping kernel module for
testing. User space support will be incorporated in
subsequent patch submissions.

Implement firmware error recovery support for Thor adapters.
This entails enabling the capability for the firmware to initiate
error recovery. Specifically, the firmware will send the reset notify
asynchronous event to notify the driver of an error and impending reset.
Subsequently, the driver will queue a task to execute the following steps.
1. Deactivate the allocated resources.
2. Await completion of the firmware's recovery process.
3. Configure the resources and reactivate the network interface.

Currently, if a media type (e.g., DAC) is hot-plugged out and another type
(e.g., optical cable) is hot-plugged in, the new speed is not reflected in
ifconfig. This occurs when the driver fails to update speeds with unchanged
tx and rx flow control.
To fix, a phy_type check ensures update of phy speeds upon detecting the new
phy.

This reduces the size of the amd64 GENERIC by about 10 KiB.
Added support for application management interface. There are two types of commands supported:
1. Firmware IOCTLs: These ioctls are meant for firmware
consumption. Driver acts as a transport for these.
2. Driver only IOCTLs: These ioctls are meant for driver
consumption. Driver will serve these ioctls without sending them down
