From 4386cc527ad879a8ef4ff8a68060f2ad3985d832 Mon Sep 17 00:00:00 2001 From: Gabor Juhos <juhosg@openwrt.org> Date: Tue, 17 Dec 2013 16:27:46 +0000 Subject: ar71xx: ag71xx: compute the RX buffer size from the maximum frame size Currently, the AG71XX_RX_PKT_SIZE value limits the received frame size to 1514/1516 bytes with/without a VLAN header respectively. However the hardware limit is controlled by the value the AG71XX_REG_MAC_MFL register which contains the value of the max_frame_len field. Compute the RX buffer size from the max_frame_len field to get rid of the 1514/1516 byte limitation. Also remove the unused AG71XX_RX_PKT_SIZE definition.
