2010-03-15be2net: fix mccq create for big endian architecturesAjit Khaparde
The request to create an mccq was being dispatched without doing a byte swap of num_pages. This byte swap is necessary for Big Endian systems like PPC. Not having this fix leads mccq create to fail on BE ASICs running newer version of firmware, thereby causing driver initialization failure.

2010-03-08be2net: remove usage of be_pci_funcAjit Khaparde
When PCI functions are virtuialized in applications by assigning PCI functions to VM (PCI passthrough), the be2net driver in the VM sees a different function number. So, use of PCI function number in any calculation will break existing code. This patch takes care of it. Signed-off-by: Ajit Khaparde <ajitk@serverengines.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-03-02be2net: fix tx completion pollingSathya Perla
In tx/mcc polling, napi_complete() is being incorrectly called before reaping tx completions. This can cause tx compl processing to be scheduled on another cpu concurrently which can result in a panic. This if fixed by calling napi complete() after tx/mcc compl processing but before re-enabling interrupts (via a cq notify).

2010-02-17be2net: don't rearm mcc cq when device is not openSathya Perla
When an MCC cmd is issued (via a netdev/ethtool op) while the device is not open, the MCC CQ gets processed but the EQ is not processed (as isr is not registered.) This can cause the EQ to become full. So, while the device is not open, CQ must not be re-armed to prevent EQ entries. Signed-off-by: Sathya Perla <sathyap@serverengines.com> Signed-off-by: David S.

2009-06-19be2net: Use MCC queue for cmds that may be called in BH contextSathya Perla
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.
