2010-05-05netdev: octeon_mgmt: Use proper MAC addresses.David Daney

2010-05-05e1000/e1000e: implement a simple interrupt moderationJesse Brandeburg
Back before e1000-7.3.20, the e1000 driver had a simple algorithm that managed interrupt moderation. The driver was updated in 7.3.20 to have the new "adaptive" interrupt moderation but we have customer requests to redeploy the old way as an option. This patch adds the old functionality back. The new functionality can be enabled via module parameter or at runtime via ethtool. Module parameter: (InterruptThrottleRate=4) to use this new moderation method. Ethtool method: ethtool -C ethX rx-usecs 4 Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.

2010-05-05e1000e: increase rx fifo size to 36K on 82574 and 82583Alexander Duyck
This change increases the RX fifo size to 36K for standard frames and decreases the TX fifo size to 4K. The reason for this change is that on slower systems the RX is much more likely to backfill and need space than the TX is. As long as the TX fifo is twice the size of the MTU we should have more than enough TX fifo.

2010-05-03forcedeth: Kill NAPI config options.David S. Miller
All distributions enable it, therefore no significant body of users are even testing the driver with it disabled. And making NAPI configurable is heavily discouraged anyways. I left the MSI-X interrupt enabling thing in an "#if 0" block so hopefully someone can debug that and it can get re-enabled. Probably it was just one of the NVIDIA chipset MSI erratas that we work handle these days in the PCI quirks (see drivers/pci/quirks.c and stuff like nvenet_msi_disable()). Signed-off-by: David S.

2010-05-03dm9601: fix phy/eeprom write routinePeter Korsgaard
Use correct bit positions in DM_SHARED_CTRL register for writes. Michael Planes recently encountered a 'KY-RS9600 USB-LAN converter', which came with a driver CD containing a Linux driver. This driver turns out to be a copy of dm9601.c with symbols renamed and my copyright stripped. That aside, it did contain 1 functional change in dm_write_shared_word(), and after checking the datasheet the original value was indeed wrong (read versus write bits). On Michaels HW, this change bumps receive speed from ~30KB/s to ~900KB/s. On other devices the difference is less spectacular, but still significant (~30%).

2010-05-03ppp_generic: handle non-linear skbs when passing them to pppdSimon Arlott
Frequently when using PPPoE with an interface MTU greater than 1500, the skb is likely to be non-linear. If the skb needs to be passed to pppd then the skb data must be read correctly. The previous commit fixes an issue with accidentally sending skbs to pppd based on an invalid read of the protocol type. When that error occurred pppd was reading invalid skb data too.

2010-05-03ppp_generic: pull 2 bytes so that PPP_PROTO(skb) is validSimon Arlott
In ppp_input(), PPP_PROTO(skb) may refer to invalid data in the skb. If this happens and (proto >= 0xc000 || proto == PPP_CCPFRAG) then the packet is passed directly to pppd. This occurs frequently when using PPPoE with an interface MTU greater than 1500 because the skb is more likely to be non-linear. The next 2 bytes need to be pulled in ppp_input(). The pull of 2 bytes in ppp_receive_frame() has been removed as it is no longer required. Signed-off-by: Simon Arlott <simon@fire.lp0.eu> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-05-03mac80211: allow controlling aggregation manuallyJohannes Berg
This allows enabling TX and disabling both TX and RX aggregation sessions manually in debugfs. It is very useful for debugging session initiation and teardown problems since with this you don't have to force a lot of traffic to get aggregation and thus have less data to analyse. Also, to debug mac80211 code itself, make hwsim "support" aggregation sessions. It will still just transfer the frame, but go through the setup and teardown handshakes.

This driver uses the core orinoco modules for the bulk of the functionality.

2010-05-03orinoco: encapsulate driver lockingDavid Kilroy
Local bus and USB drivers will need to do locking differently. The original orinoco_usb patches had a boolean variable controlling whether spin_lock_bh was used, or irq based locking.

2010-05-01net: sock_def_readable() and friends RCU conversionEric Dumazet
sk_callback_lock rwlock actually protects sk->sk_sleep pointer, so we need two atomic operations (and associated dirtying) per incoming packet. RCU conversion is pretty much needed : 1) Add a new structure, called "struct socket_wq" to hold all fields that will need rcu_read_lock() protection (currently: a wait_queue_head_t and a struct fasync_struct pointer). [Future patch will add a list anchor for wakeup coalescing] 2) Attach one of such structure to each "struct socket" created in sock_alloc_inode(). 3) Respect RCU grace period when freeing a "struct socket_wq" 4) Change sk_sleep pointer in "struct sock" by sk_wq, pointer to "struct socket_wq" 5) Change sk_sleep() function to use new sk->sk_wq instead of sk->sk_sleep 6) Change sk_has_sleeper() to wq_has_sleeper() that must be used inside a rcu_read_lock() section. 7) Change all sk_has_sleeper() callers to : - Use rcu_read_lock() instead of read_lock(&sk->sk_callback_lock) - Use wq_has_sleeper() to eventually wakeup tasks. - Use rcu_read_unlock() instead of read_unlock(&sk->sk_callback_lock) 8) sock_wake_async() is modified to use rcu protection as well. 9) Exceptions : macvtap, drivers/net/tun.c, af_unix use integrated "struct socket_wq" instead of dynamically allocated ones. They dont need rcu freeing. Some cleanups or followups are probably needed, (possible sk_callback_lock conversion to a spinlock for example...).
