2015-11-25i40e: remove BUG_ON from FCoE setupShannon Nelson
There's no need to kill the kernel thread here. If this condition was true, the probe() would have died long before we got here. In any case, we'll get the same result when this code tries to use the VSI pointer being checked. Prompted by a recent Linus diatribe.

2015-10-19i40e: Lock for VSI's MAC filter listKiran Patil
This patch introduces a spinlock which is to be used for synchronizing access to VSI's MAC filter list. This patch also synchronizes execution of other codepaths which are accessing VSI's MAC filter list with execution of service_task:sync_vsi_filters. In function i40e_add_vsi, copied out LAA MAC address instead of cloning MAC filter entry because only MAC address is needed to remove MAC VLAN filter from FW/HW.

2015-10-07i40e: make i40e_init_pf_fcoe to voidShannon Nelson
i40e_init_pf_fcoe() didn't return anything except 0, it prints enough error info already, and no driver logic depends on the return value, so this can be void.

2015-07-23i40e: use BIT and BIT_ULL macrosJesse Brandeburg
Use macros for abstracting (1 << foo) to BIT(foo) and (1ULL << foo64) to BIT_ULL(foo64) in order to match better with kernel requirements. NOTE: the adminq_cmd.h file was not modified on purpose because of the dependency upon firmware for that file.

2015-05-28i40e: fix unrecognized FCOE EOF caseVasu Dev
Because i40e_fcoe_ctxt_eof should never be called without i40e_fcoe_eof_is_supported being called first, the EOF in fcoe_ctxt_eof should always be valid and therefore we do not need to print an error if it is not valid. However, a WARN ON to easily catch any calls to i40e_fcoe_ctxt_eof that aren't preceded with a call to i40e_fcoe_eof_is_supported is helpful.

2015-04-03i40e: fix invalid void return in FCoE codeJesse Brandeburg
A function was calling i40e_tx_map with return, but tx_map returns void, and the caller returns void, so just drop the return, and everything is good.

2015-03-09i40e: Fix inconsistent use of PF/VF vs pf/vfJeff Kirsher
Joe Perches pointed out that we were inconsistent in the use of PF vs pf or VF vs vf in our driver code. Since acronyms are usually capitalized to denote that it is an acronym, changed all references to be consistent throughout the code.

2015-02-24i40e: Add support for getlink, setlink ndo opsNeerav Parikh
Add support for bridge offload ndo_ops getlink and setlink to enable bridge hardware mode as per the mode set via IFLA_BRIDGE_MODE. The support is only enabled in case of a PF VSI and not available for any other VSI type. By default the i40e driver inserts a bridge as part of the bring-up when a FDIR type VSI and/or a FCoE VSI is created. This bridge is created in VEB mode by default i.e. after creating the bridge using "Add VEB" AQ command the loopback for the PF's default VSI is enabled. The patch adds capability where all the VSIs created as downlink to the bridge inherits the loopback property and enables loopback only if the uplink bridge is operating in VEB mode. Hence, there is no need to explicitly enable loopback as part of allocating resources for SR-IOV VFs and call to do that has been removed. In case a user-request is made either via "bridge" utility or using the bridge netlink interface that requires to change the hardware bridge mode then that would require a PF reset and rebuild of the switch hierarchy. Also update the copyright year.

2015-02-09i40e: Enable Loopback for the FCOE vsi as wellAnjali Singhai Jain
