2010-05-17dm9000: fix "BUG: spinlock recursion"Baruch Siach
dm9000_set_rx_csum and dm9000_hash_table are called from atomic context (in dm9000_init_dm9000), and from non-atomic context (via ethtool_ops and net_device_ops respectively). This causes a spinlock recursion BUG. Fix this by renaming these functions to *_unlocked for the atomic context, and make the original functions locking wrappers for use in the non-atomic context.

2010-05-17r6040: fix link checking with switchesFlorian Fainelli
The current link checking logic only works for one port, which is not correct for swiches were multiple ports can have different link status. As a result we would only check for link status on port 1 of the switch. Move the calls to mii_check_media in r6040_timer which will be polling a single PHY chip correctly and assume link is up for switches.

2010-05-17gianfar: Remove legacy PM callbacksAnton Vorontsov
These callbacks were needed because dev_pm_ops support for OF platform devices was in the powerpc tree, and the patch that added dev_pm_ops for gianfar driver was in the netdev tree.

2010-05-17bnx2: Use netif_carrier_off() to prevent timeout.Michael Chan
Based on original patch from Stanislaw Gruszka <sgruszka@redhat.com>. Using netif_carrier_off() is better than updating all the ->trans_start on all the tx queues. netif_carrier_off() needs to be called after bnx2_disable_int_sync() to guarantee no race conditions with the serdes timers that can modify the carrier state. If the chip or phy is reset, carrier will turn back on when we get the link interrupt. If there is no reset, we need to turn carrier back on in bnx2_netif_start(). Again, the phy_lock prevents race conditions with the serdes timers. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: Matt Carlson <mcarlson@broadcom.com> Signed-off-by: David S.

2010-05-17netdev: bfin_mac: deduce Ethernet FCS from hardware IP payload checksumSonic Zhang
IP checksum is based on 16-bit one's complement algorithm, so to deduce a value from checksum is equal to add its complement. Unfortunately, the Blackfin on-chip MAC checksum logic only works when the IP packet has a header length of 20 bytes. This is true for most IPv4 packets, but not for IPv6 packets or IPv4 packets which use header options. So only use the hardware checksum when appropriate.

2010-05-17netdev: bfin_mac: invalid data cache only once for each new rx skb bufferSonic Zhang
The skb buffer isn't actually used until we finish transferring and pass it up to higher layers, so only invalidate the range once before we start receiving actual data. This also avoids the problem with data invalidating on Blackfin systems -- there is no invalidate-only, just invalidate+flush. So when running in writeback mode, there is the small (but not uncommon) possibility of the flush overwriting valid DMA-ed data from the cache.
