Receiver Control Register. The Receive Control register is reset by Rx Reset
signal generated by holding the TESTSELn pin low. The same signal is also
used to reset the receive MAC. The purpose of having a separate reset signal
is to be able to avoid resetting the receive MAC when the AHB bus is in a
powered down state (RESET active), and wake-up frames need to be
detected.

Pause Accept. When set, Pause frames are passed on to
the Host as regular frames. When clear, the frames are
discarded. The handling of MAC Control frames depends
on the Pause Accept bit as well as the appropriate
Individual Accept and RxFlow Control Enable bits, as
follows.
Frame discarded (do not pass the address filter)
MAC Control frames are recognized, flow control action taken,
and frames not passed to host. Non pause MAC Control
frames are passed on to host.
MAC Control frames are recognized, flow control action taken,
and all MAC control frames are passed on to host.
MAC Control frames are not distinguished from other frame
types, all frames passed on to host.
