* ar71xx: ag71xx: increase calculated max frame length valueGabor Juhos2014-01-111-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The r39147 commit introduces a regression: at lease on some routers with ar8216 switch large packets get lost if 802.1q tagged port is used on the interface connected to the aforementioned switch. The r39147 changes code in the way so interface is set to accept packets no longer than max ethernet frame length for a given mtu. Unfortunately ar8216 has a feature: it sends two additional bytes as a packet header and those this header needs to be added to the max frame length. Otherwise long enough packets get lost. The problem only manuifests itself if interface is used in vlan tagged mode. If interface is untagged then ar8216's header fits into space used by 802.1q tag and not packets are lost. Include two additional bytes in the max frame length calculation to fix the issue. This patch is tested and works with Trendnet TEW-632BRP.
