[PATCH] cs89x0 : packet reception not working

From: Jaccon Bastiaansen <hidden>
Date: 2012-08-26 21:39:06

The RxCFG register of the CS89x0 could be configured incorrectly
(because of misplaced parentheses), resulting in the disabling
of packet reception.

 }
Perhaps it would be better to use something like:

	int cfg = lp->curr_rx_cfg;

	if (lp->rx_mode == RX_ALL_ACCEPT)
		cfg |= RX_CRC_ERROR_ENBL | RX_RUNT_ENBL | RX_EXTRA_DATA_ENBL;

	writereg(dev, PP_RxCFG, cfg);
