From f887cce8de019bb32917789379af89ae4c0294ee Mon Sep 17 00:00:00 2001 From: Francois Romieu Date: Thu, 17 Jul 2008 22:24:18 +0200 Subject: r8169: multicast register update The layout of the 8101 series is identical to that of the 8168 one, thus allowing to pack everything not 8169 related above MAC_VER_06. New 810x and 8168 chipsets should automagically behave correctly. It matches code in Realtek's 1.008.00 8101 and 8.007.00 8168 drivers.

If it does not happen on first driver load it can easily be reproduced by unloading and loading the driver a few times. The magic write was added long ago by this commit: Author: François Romieu Date: Sat Jan 10 06:00:46 2004 -0500 [netdrvr r8169] Merge of changes done by Realtek to rtl8169_init_one(): - phy capability settings allows lower or equal capability as suggested in Realtek's changes; - I/O voodoo; - no need to s/mdio_write/RTL8169_WRITE_GMII_REG/; - s/rtl8169_hw_PHY_config/rtl8169_hw_phy_config/; - rtl8169_hw_phy_config(): ad-hoc struct "phy_magic" to limit duplication of code (yep, the u16 -> int conversions should work as expected); - variable renames and whitepace changes ignored. As the 8168 wasn't supported by that version this patch simply removes the bogus write from mac versions <= RTL_GIGA_MAC_VER_06.

Looks to me that the error handling code in mac80211_hwsim is awkward. Which leads to it calling ieee80211_unregister_hw even when ieee80211_register_hw failed. The function has a for loop where it generates all simulated radios. when something fails, the error handling will call mac80211_hwsim_free which frees all simulated radios who's pointer isn't zero. However the information stored is insufficient to determine whether or not the call to ieee80211_register_hw succeeded or not for a specific radio. The included patch makes init_mac80211_hwsim clean up the current simulated radio, and then calls into mac80211_hwsim_free to clean up all the radios that did succeed. This however doesn't explain why the rate control registration failed.. build tested this, but had some problems reproducing the original problem.

This requires larger dma buffers (2kb) and different alignemnt. The buffer posting logic is changed a bit. The free rx buffers are maintained in linked list, since the received reference handles can be out of order. However rx descriptors are still posted sequentially, indexed by producer.
