Since commit 0fd56bb5 ("gianfar:
Add support for skb recycling"), gianfar puts skbuffs that are in
the rx ring back onto the recycle list as-is in case there was a
receive error, but this breaks the following invariant: that all
skbuffs on the recycle list have skb->data = skb->head + NET_SKB_PAD.

The RXBUF_ALIGNMENT realignment done in gfar_new_skb() will be done
twice on skbuffs recycled in this way, causing there not to be enough
room in the skb anymore to receive a full packet, eventually leading
to an skb_over_panic from gfar_clean_rx_ring() -> skb_put().

Resetting the skb->data pointer to skb->head + NET_SKB_PAD before
putting the skb back onto the recycle list restores the mentioned
invariant, and should fix this issue.

Periodic RX interrupt needed with ICT interrupt to prevent RX race.
Sending RX interrupt require many steps to be done in the
the device:
 1- write interrupt to current index in ICT table.
 2- dma RX frame.
 3- update RX shared data to indicate last write index.
 4- send interrupt.
This could lead to RX race, driver could receive RX interrupt
but the shared data changes does not reflect that.
this could lead to RX race, RX periodic will solve this race
