I am a bit confused how the RBMR and TBMR is supposed to work. In ucc_get there is: out_be32(&ugeth->p_tx_glbl_pram->tstate, ((u32) function_code) << 24); ugeth->p_rx_glbl_pram->rstate = function_code; First, should not the rx part look the same as tx? Does programing rstate/tstate replace RBMR and TBMR?
