[PATCH net] net: broadcom: bcm4908_enet: enable RX after processing packets

[Rafał Miłecki]

From: Rafał Miłecki <ra...@milecki.pl>

When receiving a lot of packets hardware may run out of free
descriptiors and stop RX ring. Enable it every time after handling
received packets.

Fixes: 4feffeadbcb2 ("net: broadcom: bcm4908enet: add BCM4908 controller 
driver")
