2013-06-05Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/netDavid S. Miller
Merge 'net' bug fixes into 'net-next' as we have patches that will build on top of them. This merge commit includes a change from Emil Goode (emilgoode@gmail.com) that fixes a warning that would have been introduced by this merge. Specifically it fixes the pingv6_ops method ipv6_chk_addr() to add a "const" to the "struct net_device *dev" argument and likewise update the dummy_ipv6_chk_addr() declaration.

2013-05-31be2net: Implement initiate FW dump feature for LancerSomnath Kotur

2013-05-30be2net: Fix crash on 2nd invocation of PCI AER/EEH error_detected hookSomnath Kotur
During a PCI EEH/AER error recovery flow, if the device did not successfully restart, the error_detected() hook may be called a second time with a "perm_failure" state. This patch skips over driver cleanup for the second invocation of the callback. Also, Lancer error recovery code is fixed-up to handle these changes.

2013-05-23be2net: bug fix on returning an invalid nic descriptorWei Yang
In function be_get_nic_desc(), it will go through the descriptor array returned from f/w. By comparing the desc_type field, it determines whether there is a nic descriptor in the array or not. In the case of no nic descriptor, this function should return NULL. The code may return an invalide descriptor, when there is no nic descriptor in the array and the desc_count is less than MAX_RESOURCE_DESC. In this case, even there is no nic descriptor, it will still return the lase descriptor since the i doesn't equal to MAX_RESOURCE_DESC. This patch fix this issue by returning the descriptor when find it and return NULL for other cases.

2013-03-06benet: Wait f/w POST until timeoutGavin Shan
While PCI card faces EEH errors, reset (usually hot reset) is expected to recover from the EEH errors. After EEH core finishes the reset, the driver callback (be_eeh_reset) is called and wait the firmware to complete POST successfully. The original code would return with error once detecting failure during POST stage. That seems not enough. The patch forces the driver (be_eeh_reset) to wait the firmware completes POST until timeout, instead of returning error upon detection POST failure immediately. Also, it would improve the reliability of the EEH funtionality of the driver.

2013-02-04be2net: fix re-loaded PF driver to re-gain control of its VFsSathya Perla
Currently, when the PF driver is unloaded and re-loaded while VFs are attached to VMs, it loses control of its VFs. The PF driver now uses the newly defined/created GET_IFACE_LIST cmd (available in FW ver >= 4.6) to query the if_id of the VFs (enabled in its previous life). The PF driver then uses the if_id for further VF configuration. The GET_IFACE_MAC_LIST cmd has also implemented in BE3 FW for PF to query pmac-ids used by its VFs.
