Increase the rx ring size (LAN743X_RX_RING_SIZE) to improve rx performance
on some platforms.

Tested on x86 PC with EVB-LAN7430.
The iperf3.7 TCPIP improved from 881 Mbps to 922 Mbps, and UDP improved
from 817 Mbps to 936 Mbps.

You seem to be posting performance optimizations as fixes.
800Mbps is not "broken" for a 1G interface. Please remove the Fixes tag and re-
post this with [PATCH net-next].

Thank you!
Hi Jakub,
no problem.
Thank you for your comment.
