David C Somayajulu 16a38a930d When an mbuf allocation fails in the receive path, the mbuf containing the received packet is not sent to the host net 
work stack and is reused again on the receive ring.  Remaining received packets in the ring are not processed in that
invocation of bxe_rxeof() and defered to the task thread.

* Post a slowpath command.
*
* A slowpath command is used to propogate a configuration change through
* the controller in a controlled manner, allowing each STORM processor and
* other H/W blocks to phase in the change. The commands sent on the
* slowpath are referred to as ramrods. Depending on the ramrod used the
* completion of the ramrod will occur in different ways. Here's a
* breakdown of ramrods and how they complete:
*
* RAMROD_CMD_ID_ETH_PORT_SETUP
* Used to setup the leading connection on a port. Completes on the
* Receive Completion Queue (RCQ) of that port (typically fp[0]).
*
* RAMROD_CMD_ID_ETH_CLIENT_SETUP
* Used to setup an additional connection on a port. Completes on the
* RCQ of the multi-queue/RSS connection being initialized.
*
* RAMROD_CMD_ID_ETH_STAT_QUERY
* Used to force the storm processors to update the statistics database
* in host memory. This ramrod is send on the leading connection CID and
* completes as an index increment of the CSTORM on the default status
* block.
*
* RAMROD_CMD_ID_ETH_UPDATE
* Used to update the state of the leading connection, usually to udpate
* the RSS indirection table. Completes on the RCQ of the leading
* connection. (Not currently used under FreeBSD until OS support becomes
* available.)
*
* RAMROD_CMD_ID_ETH_HALT
* Used when tearing down a connection prior to driver unload. Completes
* on the RCQ of the multi-queue/RSS connection being torn down. Don't
* use this on the leading connection.
*
* RAMROD_CMD_ID_ETH_SET_MAC
* Sets the Unicast/Broadcast/Multicast used by the port. Completes on
* the RCQ of the leading connection.
*
* RAMROD_CMD_ID_ETH_CFC_DEL
* Used when tearing down a conneciton prior to driver unload. Completes
* on the RCQ of the leading connection (since the current connection
* has been completely removed from controller memory).
*
* RAMROD_CMD_ID_ETH_PORT_DEL
* Used to tear down the leading connection prior to driver unload,
* typically fp[0]. Completes as an index increment of the CSTORM on the
* default status block.
*
* RAMROD_CMD_ID_ETH_FORWARD_SETUP
* Used for connection offload. Completes on the RCQ of the multi-queue
* RSS connection that is being offloaded. (Not currently used under
* FreeBSD.)
*
* There can only be one command pending per function.
*
* Returns:
* 0 = Success, !0 = Failure.

* In E2 there is a bug in the timers block that can cause function 6 / 7
* (i.e. vnic3) to start even if it is marked as "scan-off".
* This occurs when a different function (func2,3) is being marked
* as "scan-off". Real-life scenario for example: if a driver is being
* load-unloaded while func6,7 are down. This will cause the timer to access
* the ilt, translate to a logical address and send a request to read/write.
* Since the ilt for the function that is down is not valid, this will cause
* a translation error which is unrecoverable.
* The Workaround is intended to make sure that when this happens nothing
* fatal will occur. The workaround:
* 1. First PF driver which loads on a path will:
* a. After taking the chip out of reset, by using pretend,
* it will write "0" to the following registers of
* the other vnics.
* REG_WR(pdev, PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER, 0);
* REG_WR(pdev, CFC_REG_WEAK_ENABLE_PF,0);
* REG_WR(pdev, CFC_REG_STRONG_ENABLE_PF,0);
* And for itself it will write '1' to
* PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable
* dmae-operations (writing to pram for example.)
* note: can be done for only function 6,7 but cleaner this
* way.
* b. Write zero+valid to the entire ILT.
* c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
* VNIC3 (of that port). The range allocated will be the
* entire ILT. This is needed to prevent ILT range error.
* 2. Any PF driver load flow:
* a. ILT update with the physical addresses of the allocated
* logical pages.
* b. Wait 20msec. - note that this timeout is needed to make
* sure there are no requests in one of the PXP internal
* queues with "old" ILT addresses.
* c. PF enable in the PGLC.
* d. Clear the was_error of the PF in the PGLC. (could have
* occurred while driver was down)
* e. PF enable in the CFC (WEAK + STRONG)
* f. Timers scan enable
* 3. PF driver unload flow:
* a. Clear the Timers scan_en.
* b. Polling for scan_on=0 for that PF.
* c. Clear the PF enable bit in the PXP.
* d. Clear the PF enable in the CFC (WEAK + STRONG)
* e. Write zero+valid to all ILT entries (The valid bit must
* stay set)
* f. If this is VNIC 3 of a port then also init
* first_timers_ilt_entry to zero and last_timers_ilt_entry
* to the last enrty in the ILT.
*
* Notes:
* Currently the PF error in the PGLC is non recoverable.
* In the future the there will be a recovery routine for this error.
* Currently attention is masked.
* Having an MCP lock on the load/unload process does not guarantee that
* there is no Timer disable during Func6/7 enable. This is because the
* Timers scan is currently being cleared by the MCP on FLR.
* Step 2.d can be done only for PF6/7 and the driver can also check if
* there is error before clearing it. But the flow above is simpler and
* more general.
* All ILT entries are written by zero+valid and not just PF6/7
* ILT entries since in the future the ILT entries allocation for
* PF-s might be dynamic.
