2009-06-19be2net: Use MCC queue for cmds that may be called in BH contextSathya Perla1-17/+52
Currenlty multicast_set and promiscuous_config cmds -- that may be called in BH context -- use the blocking MCC mbox to post cmds. An mbox cmd is protected via a spin_lock(cmd_lock) and not spin_lock_bh() as it is undesirable to disable BHs while a blocking mbox cmd is in progress (and take long to finish.) This can lockup a cmd in progress in process context. So, these two cmds in BH context must use the MCC queue to post cmds.

2009-06-19be2net: Add MCC queue mechanism for BE cmdsSathya Perla5-161/+455
Currenlty all cmds use the blocking MCC mbox to post cmds. An mbox cmd is protected via a spin_lock(cmd_lock) and not spin_lock_bh() as it is undesirable to disable BHs while a blocking mbox cmd is in progress (and take long to finish.) This can lockup a cmd in progress in process context. Instead cmds that may be called in BH context must use the MCC queue to post cmds. The cmd completions are rcvd in a separate completion queue and the events are placed in the tx-event queue. Signed-off-by: Sathya Perla <sathyap@serverengines.com> Signed-off-by: David S.

2009-06-19af_iucv: Return -EAGAIN if iucv msg limit is exceededHendrik Brueckner2-43/+103
If the iucv message limit for a communication path is exceeded, sendmsg() returns -EAGAIN instead of -EPIPE. The calling application can then handle this error situtation, e.g. to try again after waiting some time. For blocking sockets, sendmsg() waits up to the socket timeout before returning -EAGAIN. For the new wait condition, a macro has been introduced and the iucv_sock_wait_state() has been refactored to this macro.

2009-06-18netxen: fix tx ring accountingDhananjay Phadke4-21/+35
This forces every update of tx ring producer to check for availability of space for next full TSO command. Earlier firmware control commands didn't care to pause tx queue. Stop the tx queue if there's not enough space to transmit one full LSO command left on the tx ring after current transmit. This avoids returning NETDEV_TX_BUSY after checking distance between producer and consumer on every cpu. Restart the tx queue only if we have cleaned up enough tx descriptors.

If the adapter is not power-manageable using either ACPI, or the native PCI PM interface, __e100_power_off() returns error code, which causes every attempt to suspend to fail, although it should return 0 in such a case.

2009-06-18net: group address list and its countJiri Pirko9-90/+89
This patch is inspired by patch recently posted by Johannes Berg. Basically what my patch does is to group list and a count of addresses into newly introduced structure netdev_hw_addr_list. This brings us two benefits: 1) struct net_device becames a bit nicer. 2) in the future there will be a possibility to operate with lists independently on netdevices (with exporting right functions). I wanted to introduce this patch before I'll post a multicast lists conversion.

2009-06-18ipv4: Fix fib_trie rebalancing, part 2Jarek Poplawski1-14/+10
My previous patch, which explicitly delays freeing of tnodes by adding them to the list to flush them after the update is finished, isn't strict enough. It treats exceptionally tnodes without parent, assuming they are newly created, so "invisible" for the read side yet. But the top tnode doesn't have parent as well, so we have to exclude all exceptions (at least until a better way is found). Additionally we need to move rcu assignment of this node before flushing, so the return type of the trie_rebalance() function is changed.

2009-06-17net: sk_wmem_alloc has initial value of one, not zeroEric Dumazet7-16/+41
commit 2b85a34e911bf483c27cfdd124aeb1605145dc80 (net: No more expensive sock_hold()/sock_put() on each tx) changed initial sk_wmem_alloc value. Some protocols check sk_wmem_alloc value to determine if a timer must delay socket deallocation. We must take care of the sk_wmem_alloc value being one instead of zero when no write allocations are pending. Reported by Ingo Molnar, and full diagnostic from David Miller.

2009-06-16sky2: don't look for VPD sizeStephen Hemminger1-15/+16
The code to compute VPD size didn't handle some systems that use chip without VPD. Also some of the newer chips use some additional registers to store the actual size, and wasn't worth putting the additional complexity in, so just remove the code. No big loss since the code to set the VPD size was only a convenience so that utilities would not read the extra space past the end of the available VPD.
