bnx2x: Load/Unload under traffic
Load/Unload under traffic Few issues were found when loading and unloading under traffic: - When receiving Tx interrupt call netif_wake_queue if the queue is stopped but the state is open - Check that interrupts are enabled before doing anything else on the msix_fp_int function - In nic_load, enable the interrupts only when needed and ready for it - Function stop_leading returns status since it can fail - Add 1ms delay when unloading the driver to validate that there are no open transactions that already started by the FW - Splitting the "has work" function into Tx and Rx so the same function will be used on unload and interrupts - Do not request for WoL if only resetting the device (save the time that it takes the FW to set the link after reset) - Fixing the device reset after iSCSI boot and before driver load - all internal buffers must be cleared before the driver is loaded Signed-off-by: Vladislav Zolotarov <vladz@broadcom.com> Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.
