net: fec: Allow reception of frames bigger than 1522 bytes
The FEC Receive Control Register has a 14 bit field indicating the longest frame that may be received. It is being set to 1522. Frames longer than this are discarded, but counted as being in error. When using DSA, frames from the switch has an additional header, either 4 or 8 bytes if a Marvell switch is used. Thus a full MTU frame of 1522 bytes received by the switch on a port becomes 1530 bytes when passed to the host via the FEC interface. Change the maximum receive size to 2048 - 64, where 64 is the maximum rx_alignment applied on the receive buffer for AVB capable FEC cores. Use this value also for the maximum receive buffer size. The driver is already allocating a receive SKB of 2048 bytes, so this change should not have any significant effects. Tested on imx51, imx6, vf610.
