* be2net: pass if_id for v1 and V2 versions of TX_CREATE cmdVasundhara Volam2013-10-181-1/+2
| | | | | | | | | | It is a required field for all TX_CREATE cmd versions > 0. This fixes a driver initialization failure, caused by recent SH-R Firmwares (versions > 10.0.639.0) failing the TX_CREATE cmd when if_id field is not passed.

| | | | | | | | | | When the interface runs out of the allocated entries in VLAN table, we program the interface in VLAN promiscuous mode.

* be2net: Fix be_cmd_if_create() to use MBOX if MCCQ is not createdSathya Perla2013-08-271-24/+85
| | | | | | | | | | | | Currently the IF_CREATE FW cmd is issued only *after* MCCQ is created as it was coded to only use MCCQ. By fixing this, cmd_if_create() can be called before MCCQ is created and the same routine for VF provisioning can be called after. This allows for consolidating all the queue create routines by moving the be_cmd_if_create() call above all queue create calls in be_setup().

* be2net: bug fix on returning an invalid nic descriptorWei Yang2013-05-231-9/+4
| | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* be2net: fix be_close() to ensure all events are ack'edSathya Perla2012-12-181-0/+5
| | | | | | | | | | | In be_close(), be_eq_clean() must be called after all RX/TX/MCC queues have been cleaned to ensure that any events caused while cleaning up completions are notified/acked. Not clearing all events can cause upredictable behaviour when RX rings are re-created in the subsequent be_open(). Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

* be2net: fix access to SEMAPHORE regSathya Perla2012-11-071-6/+5
| | | | | | | | | The SEMAPHORE register was being accessed from the csr BAR space. This BAR may not be available in some Skyhawk-R configurations. Instead, access this register via the PCI config space (it's available there too). Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* be2net: fix wrong usage of adapter->generationSathya Perla2012-11-071-2/+4
| | | | | | | | adapter->generation was being incorrectly set as BE_GEN3 for Skyhawk-R. Replace generation usage with XXX_chip() macros to identify the chip. Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | FW flashing code, even though it works correctly, makes some hidden assumptions about buffer sizes. This is causing code analysers to report error. Cleanup FW flashing code to remove these hidden assumptions.
