Before FW introduced the JUMP_FDB_RX action feature, jump from
FDB Tx to Rx is not allowed. JUMP_FDB_RX feature introduces
the internal loopback for Tx case and allow the REG C0 C1 B be
preserved as well.

This commit adds the JUMP_FDB_RX cap bit check and use
JUMP_FDB_RX instead of FT for dest table FDB Rx case.
