Packet should not be accessed after signaling hardware to
process it. There might be a case where, that packet is freed
by the other CPU.

The spin_lock() used in edma_read_append_stats() API can
potentially result in a deadlock as it is being called
from process context and softirq context.

Replacing spin_lock() with spin_lock_bh() will allow
critical section to run without getting interrupted.

probe API is registering the netdev way before allocating
the phydev(which is getting accessed in netdev callback APIs).
Ideally probe function should allocate all the required resources
before registering the netdev.

Changes include adding new value (2) to edma_disable_rss sysctl interface
to disable RSS and also to enable ACL.  It also indicates that Rx priority
from switch is different between RSS enable case and RSS disable, ACL enable
case.

Core3 CPU utilization was shooting up when TX queues
were stopped due to unavailability of HW descriptors.
This was causing TX packets for Core1 to be processed
on Core3 thereby causing apparent hike in CPU utilization.
This code adds support to make queue stopping configurable
