Bug Description
[Impact]
rx performance is sub-optimal with EVB-LAN7430 NICs.
[Test Case]
Use iperf3 to submit TCP or UDP traffic to a host w/ a EVB-LAN7430 NIC.
[Fix]
Cherry-pick the following upstream commit:
a1f1627540cde net: ethernet: microchip: lan743x: Increase rx ring size to improve rx performance
[What could go wrong]
The patch will slightly increase memory usage, which could possibly add memory pressure to memory-restricted systems.

Due to lack of hardware, we are unable to verify a backport of this fix, so I'll go ahead and mark this bug "Won't Fix". If you are impacted by this and are able to perform the necessary performance testing to verify a backport, please reopen and we can move forward.
