Randall Stewart ded5ea6a25 This fixes a out-of-order problem with several 
of the newer drivers. The basic problem was
that the driver was pulling the mbuf off the
drbr ring and then when sending with xmit(), encounting
a full transmit ring. Thus the lower layer
xmit() function would return an error, and the
drivers would then append the data back on to the ring.
For TCP this is a horrible scenario sure to bring
on a fast-retransmit.

The fix is to use drbr_peek() to pull the data pointer
but not remove it from the ring. If it fails then
we either call the new drbr_putback or drbr_advance
method. Advance moves it forward (we do this sometimes
when the xmit() function frees the mbuf). When
we succeed we always call advance. The
putback will always copy the mbuf back to the top
of the ring. Note that the putback *cannot* be used
with a drbr_dequeue() only with drbr_peek(). We most
of the time, in putback, would not need to copy it
back since most likey the mbuf is still the same, but
sometimes xmit() functions will change the mbuf via
a pullup or other call. So the optimial case for
the single consumer is to always copy it back. If
we ever do a multiple_consumer (for lagg?) we
will  need a test and atomic in the put back possibly
a seperate putback_mc() in the ring buf.

* 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.
