2008-06-27CONNECTOR: add a proc entry to list connectorsLi Zefan
I got a problem when I wanted to check if the kernel supports process event connector, and It seems there's no way to do this check. At best I can check if the kernel supports connector or not, by looking into /proc/net/netlink, or maybe checking the return value of bind() to see if it's ENOENT. So it would be useful to add /proc/net/connector to list all supported connectors: # cat /proc/net/connector Name ID connector 4294967295:4294967295 cn_proc 1:1 w1 3:1 Changelog: - fix memory leak: s/seq_release/single_release - use spin_lock_bh instead of spin_lock_irqsave Signed-off-by: Li Zefan <lizf@cn.fujitsu.com> Acked-by: Evgeniy Polyakov <johnpol@2ka.mipt.ru> Signed-off-by: David S.

2008-06-27rt2x00: Fix lock dependency errrorIvo van Doorn
This fixes a circular locking dependency in the workqueue handling. The interface work task uses the mac80211 function ieee80211_iterate_active_interfaces() which grabs the RTNL lock. However when the interface is brough down, this happens under the RTNL lock as well, this causes problems because mac80211 will flush the workqueue during the ifdown event. This causes mac80211 to wait until the driver has completed all work which can't finish because it is waiting on the RTNL lock. This is fixed by moving rt2x00 workqueue tasks on a different workqueue, this workqueue can be flushed when the ieee80211_hw structure is removed by the driver (when the driver is unloaded) which does not happen under the RTNL lock.

2008-06-27[netdrvr] Fix IOMMU overflow checking in s2io.cAndi Kleen
s2io has IOMMU overflow checking, but unfortunately it is wrong. It didn't use the standard macros, which meant that it only worked on POWER and SPARC because only those define DMA_ERROR_CODE. Convert it to use the standard macros instead. I also commented two more bugs in the IOMMU handling. It assumes that 0 DMA addresses cannot happen, but that's not true in all IOMMU setups. The information if a buffer has been already mapped needs to be stored elsewhere. Didn't fix those because it needs careful checking of the buffer handling by the maintainers.

The TPA stands for Transparent Packet Aggregation. When enabled, the FW aggregate in-order TCP packets according to the 4-tuple match and sends 1 big packet to the driver. This packet is stored on an SGL in which each SGE is 1 page. The FW also implements a timeout algorithm and it honors all TCP flag, including the push flag as a trigger to halt aggregation. After receiving Ben Hutchings comments, we also added ethtool support, so now, thanks to Ben's patch, when forwarding is enabled, our aggregation is turned off using the LRO flags.

This new initialization code supports the 57711 HW.

The initialization is done via DMAE after the DMAE block is ready - before it is ready, some of the initialization is done via PCI configuration transactions (referred to as indirect write). A mutex to protect the DMAE from being overlapped was added. There are few new registers which needs to be initialized by SW - the full comment for those registers is added to the register file.
