* ethtool: cosmetic: Use ethtool ethtool_cmd_speed APIDavid Decotigny2011-04-291-13/+12
| | | | | | | | | | | | | | | | | | | | This updates the network drivers so that they don't access the ethtool_cmd::speed field directly, but use ethtool_cmd_speed() instead. For most of the drivers, these changes are purely cosmetic and don't fix any problem, such as for those 1GbE/10GbE drivers that indirectly call their own ethtool get_settings()/mii_ethtool_gset(). The changes are meant to enforce code consistency and provide robustness with future larger throughputs, at the expense of a few CPU cycles for each ethtool operation. All drivers compiled with make allyesconfig ion x86_64 have been updated.

* cassini: Use local-mac-address prom property for Cassini MAC addressRichard Mortimer2011-01-061-0/+16
| | | | | | | | | | | | | | | | | | | | Fallback on the local-mac-address prom property if the Cassini device does not have an address programmed in the VPD ROM. This uses the same technique as implemented by the sungem driver. The problem was reported by Frans van Berckel using Debian kernel 2.6.34-7 on Sun Fire V440. udev was assigning a new eth<n> device name on each reboot because the cassini driver was using a random MAC address. Fix tested on 2.6.34-7 and 2.6.37 Sun Fire V440.

* net: Fix drivers advertising HW_CSUM feature to use csum_startMichał Mirosław2010-12-161-1/+1
| | | | | | | | | | | | Some drivers are using skb_transport_offset(skb) instead of skb->csum_start for NETIF_F_HW_CSUM offload. This does not matter now, but if someone implements checksumming of encapsulated packets then this will break silently.

* drivers/net: don't use flush_scheduled_work()Tejun Heo2010-12-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | flush_scheduled_work() is on its way out. This patch contains simple conversions to replace flush_scheduled_work() usage with direct cancels and flushes. Directly cancel the used works on driver detach and flush them in other cases. The conversions are mostly straight forward and the only dangers are, * Forgetting to cancel/flush one or more used works. * Cancelling when a work should be flushed (ie. the work must be executed once scheduled whether the driver is detaching or not).

* mm: speculative page referencesNick Piggin2008-07-261-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we can be sure that elevating the page_count on a pagecache page will pin it, we can speculatively run this operation, and subsequently check to see if we hit the right page rather than relying on holding a lock or otherwise pinning a reference to the page. This can be done if get_page/put_page behaves consistently throughout the whole tree (ie. if we "get" the page after it has been used for something else, we must be able to free it with a put_page). Actually, there is a period where the count behaves differently: when the page is free or if it is a constituent page of a compound page. We need an atomic_inc_not_zero operation to ensure we don't try to grab the page in either case. This patch introduces the core locking protocol to the pagecache (ie. adds page_cache_get_speculative, and tweaks some update-side code to make it work). Thanks to Hugh for pointing out an improvement to the algorithm setting page_count to zero when we have control of all references, in order to hold off speculative getters.

* [CASSINI]: Fix endianness bug.Al Viro2008-01-041-3/+5
| | | | | | | | | | | | | | | | | | | Here's proposed fix for RX checksum handling in cassini; it affects little-endian working with half-duplex gigabit, but obviously needs testing on big-endian too. The problem is, we need to convert checksum to fixed-endian *before* correcting for (unstripped) FCS. On big-endian it won't matter (conversion is no-op), on little-endian it will, but only if FCS is not stripped by hardware; i.e. in half-duplex gigabit mode when ->crc_size is set. cassini.c part is that fix, cassini.h one consists of trivial endianness annotations. With that applied the sucker is endian-clean, according to sparse. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
