* 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.

| | | | | | | | | | | | | The currently used bitmask of the maximum frame length field is wrong for both models. On AR724x/AR933x the largest frame size is 2047 bytes, on the AR934x it is 16383 bytes. Make the MTU setup code model specific, and use the correct bitmask for both models.

* ar71xx: ag71xx: compute the RX buffer size from the maximum frame sizeGabor Juhos2013-12-172-3/+1
| | | | | | | | | | | | | | | | 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: use mdio bus name in ar7240_probe messagesGabor Juhos2013-12-171-4/+4
| | | | | | | | | | | | | | | The ar7240_probe function uses the network device name in the kernel log messages, however the name is not yet initialized when the ar7240_probe function is called.

* ag71xx: ag71xx: use device name for debugfs entryGabor Juhos2013-12-171-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | The ag71xx debugfs code uses the network device name for the device specific debugfs directory. Since r38689 'ar71xx: ag71xx: fix a race involving netdev registration' the debugfs initialization happens before the ethernet device gets registered and the network device name contains 'eth%d' at this point. If the board setup code registers multiple ag71xx devices, the debugfs code tries to create the device specific dir with the same name which causes an error like this: eth0: Atheros AG71xx at 0xba000000, irq 5, mode:GMII ag71xx ag71xx.0: connected to PHY at ag71xx-mdio.1:04 [uid=004dd041, driver=Generic PHY] ag71xx: probe of ag71xx.0 failed with error -12 Use the device name for the debugfs directory to avoid the collisions. Also add an error message and change the return code if the debugfs_create_dir call fails.

* ar71xx: ag71xx: fix a race involving netdev registrationGabor Juhos2013-11-082-23/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In particular, phy_connect before register_netdev. This is because register_netdev runs the netdev notifiers, which can race with the rest of the initialization in ag71xx_probe. In my case this manifested in two ways: 1) If ag71xx is compiled as a module and inserted after netifd has started, netifd is notified by register_netdev before the call to ag71xx_phy_connect. netifd tries to bring the interface up, which calls ag71xx_open, which in turn enters ag71xx_phy_start. This keys off ag->phy_dev (which is still NULL) and thinks this is a fixed-link board, and enters ag71xx_link_adjust. This looks at ag->speed which is not yet initialized and hits the BUG() in the switch (ag->speed) in ag71xx_link_adjust. This is the wrong code path for ag71xx_phy_start - my board has PHYs that need to be brought up with phy_start. Doing ag71xx_phy_connect before register_netdev ensures that ag->phy_dev is non-NULL before ag71xx_phy_start is ever called. 2) When ag71xx is built into the kernel, and netconsole is enabled, there is a gap in the initial burst of replayed printks right after the netdev comes up. My assumption is that netconsole is also triggered by a netdev notifier, and part of this printk burst happens before the call into ag71xx_phy_connect, so part of the burst is lost while the PHY comes up. This patch fixes the gap - all the printks before eth0 comes up are bursted in full when netconsole initializes. ag71xx_phy_connect_xxx no longer runs with a registered netdev, so the logging has been adjusted accordingly to avoid "unregistered net_device" or "eth%d" messages in dmesg.
