Bits 0-7: Receive Maximum Packet Size (RMX[8:15]) These sixteen bits indicate the maximum allowable packet
size in bytes. The size includes the FCS bytes, but excludes bit/byte stuffing. Note: If the maximum packet size is
less than the minimum packet size, all packets are discarded. When packet processing is disabled, these sixteen
bits indicate the "packet" size the incoming data is to be broken into.
The maximum packet size allowable is 2016 bytes plus the FCS bytes. Any values programmed that are greater
than 2016 + FCS will have the same effect as 2016+ FCS value.
In X.86 mode, the X.86 encapsulation bytes are included in maximum size control.

Bit 2: Receive FCS Errored Packet Count (REPC) This read only bit indicates that the receive FCS errored
packet count is nonzero.
Bit 1: Receive Aborted Packet Count (RAPC) This read only bit indicates that the receive aborted packet count
is nonzero.
Bit 0: Receive Size Violation Packet Count (RSPC) This read only bit indicates that the receive size violation
packet count is nonzero.
