Thanks guys, here an updated version then, before linkwatch surgery ? In this version, I force the event to be sent synchronously. [PATCH net-next-2.6] linkwatch: linkwatch_forget_dev() to speedup device dismantle time ip link del eth3.103 ; time ip link del eth3.104 ; time ip link del eth3.105 real 0m0.266s user 0m0.000s sys 0m0.001s real 0m0.770s user 0m0.000s sys 0m0.000s real 0m1.022s user 0m0.000s sys 0m0.000s One problem of current schem in vlan dismantle phase is the holding of device done by following chain : vlan_dev_stop() -> netif_carrier_off(dev) -> linkwatch_fire_event(dev) -> dev_hold() ... And __linkwatch_run_queue() runs up to one second later... A generic fix to this problem is to add a linkwatch_forget_dev() method to unlink the device from the list of watched devices. dev->link_watch_next becomes dev->link_watch_list (and use a bit more memory), to be able to unlink device in O(1).

2009-11-17macvlan: Precise RX stats accountingEric Dumazet
With multi queue devices, its possible that several cpus call macvlan RX routines simultaneously for the same macvlan device. We update RX stats counter without any locking, so we can get slightly wrong counters. One possible fix is to use percpu counters, to get precise accounting and also get guarantee of no cache line ping pongs between cpus.

2009-11-17net: Getting rid of the x86 dependency to built vmxnet3Shreyas Bhatewara
This patch removes config dependency on x86 to build vmxnet3 driver. Thus the driver can be built on big endian architectures now. Although vmxnet3 is not supported on VMs other than x86 architecture, all this code goes in to ensure correctness. If the code is not dependent on x86, it should not assume little endian architecture in any of its operations. Signed-off-by: Shreyas Bhatewara <sbhatewara@vmware.com> Signed-off-by: David S.

2009-11-16ppp: fix BUG on non-linear SKB (multilink receive)Ben McKeegan
PPP does not correctly call pskb_may_pull() on all necessary receive paths before reading the PPP protocol, thus causing PPP to report seemingly random 'unsupported protocols' and eventually trigger BUG_ON(skb->len < skb->data_len) in skb_pull_rcsum() when receiving multilink protocol in non-linear skbs. ppp_receive_nonmp_frame() does not call pskb_may_pull() before reading the protocol number. For the non-mp receive path this is not a problem, as this check is done in ppp_receive_frame(). For the mp receive path, ppp_mp_reconstruct() usually copies the data into a new linear skb. However, in the case where the frame is made up of a single mp fragment, the mp header is pulled and the existing skb used. This skb was then passed to ppp_receive_nonmp_frame() without checking if the encapsulated protocol header could safely be read.

2009-11-16rt2800: do not enable tbtt unless we are in a beacon modeJosef Bacik
Please be gentle, I'm a fs developer and this is my first foray into drivers, as I'm tired of building ralinks driver everytime I update my kernel. Whenever I load the rt2800pci driver my box bogs down, and a few printk's later I discovered its because I was getting 10's of thousands of TBTT interrupts a second. I discovered this was because we were setting the beacon timer to 0, which is apparently what TBTT keys off of. It seems to me that we should only be enabling TBTT when we are in a beacon transmitting mode, which from what I can tell is in AD-HOC and other such modes where the mac80211 layer would have given us a proper beacon_int to set the beacon timer to instead of 0. So this is my fix, only enable TBTT if our sync mode is for beacon. This makes it so my box doesn't die everytime I load the rt2800pci driver. Let me know if this is acceptable, I just learned all these terms about 15 minutes ago via wikipedia, so I really am not familiar with how this stuff is supposed to work.
