* ar71xx: fix ethernet FIFO state corruption on ar7240Felix Fietkau2011-08-042-20/+61
| | | | | | | | | When starting/stopping DMA sometimes the FIFO state gets corrupted, leading to wildly fluctuating latencies or packet data corruption. Fix this by issuing a fast MAC reset as soon as the link is detected as up. Fixes #9689, #9405 SVN-Revision: 27896
* ag71xx: fix memory corruption issues on ar7240 on ethernet start/stopFelix Fietkau2011-08-042-3/+19
| | | | | | | | | | | When the DMA engine state gets corrupted due to a hardware issues, it often won't stop rx until a full reset is issued. In that case the hardware must keep a valid descriptor, otherwise it will write to random places in system RAM, triggering random crashes. To fix this, keep a dummy descriptor without a buffer that keeps the DMA engine in a sane state until the reset is done SVN-Revision: 27895

* ar71xx: Fix header offset for newer WRT160NL modelsGabor Juhos2011-05-311-9/+16
| | | | | | | | | | | | Newer WRT160NLs have a flash chip with 4K erase blocks instead of 64K, resulting in miscalculated partition sizes. Since the actual sizes did not change, hardcode them to their current sizes, and make sure they are at least one erase block big (in case Cisco decides to start to use chips with 128K erase blocks).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reading of the PHY registers occasionally returns with bogus values under heavy load. This misleads the PHY driver and thus causes false link/speed change notifications which leads to performance loss. This is easily noticable during an iperf session: ...

* ar71xx: ag71xx: fix section mismatch warningsGabor Juhos2011-05-082-2/+2
| | | | | | | | | | | | | | | | | | The function __devinit ag71xx_probe() references a function __devexit ag71xx_phy_disconnect(). This is often seen when error handling in the init function uses functionality in the exit path. The fix is often to remove the __devexit annotation of ag71xx_phy_disconnect() so it may be used outside an exit section. The function ag71xx_phy_disconnect() references a function in an exit section. Often the function ag71xx_ar7240_cleanup() has valid usage outside the exit section and the fix is to remove the __devexit annotation of ag71xx_ar7240_cleanup. SVN-Revision: 26855
