* ar71xx: split packets into multiple descriptors on ar716xFelix Fietkau2014-08-291-3/+7
| | | | | | | | | | | This improves performance when doing concurrent rx/tx on a single ethernet MAC, e.g. when routing between VLANs. Fixes #13072 Signed-off-by: Felix Fietkau <nbd@openwrt.org> SVN-Revision: 42328
* ar71xx: ag71xx: store descriptor packet length mask in ag71xx structGabor Juhos2013-12-201-5/+1
| | | | | | | | | | | | | | | The currently used bitmask is not correct for all SoCs. Introduce a new field in struct ag71xx and store the bitmask in that. Use the current value for now, it will be adjusted for each SoCs in further patches. Aslo use the new field directly in the ag71xx_rx_packets and ag71xx_hard_start_xmit() functions and remove the ag71xx_desc_pktlen() helper.

* ar71xx: ag71xx: compute the RX buffer size from the maximum frame sizeGabor Juhos2013-12-171-2/+0
| | | | | | | | | | | | | | | | 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.

* ar71xx: ag71xx: store maximum frame length in the ag71xx structGabor Juhos2013-12-171-0/+2
