Routine Description:
Send Net Buffer List handler
This function is an optional function for filter drivers. If provided, NDIS
will call this function to transmit a linked list of NetBuffers, described by a
NetBuferList, over the network. If this handler is NULL, NDIS will skip calling
this fitler when sending a NetBufferList and will call the next lower fitler
in the stack with a non_NULL FilterSendNetBufferList handleror the miniport driver.
A filter that doesn't provide a FilerSendNetBufferList handler can not initiate a
send o its own.
Arguments:
FilterModuleContext: Pointer to our filter context area.
NetBufferLists: Pointer to a List of NetBufferLists.
PortNumber - Port Number to which this send is targetted
SendFlags- Specifies if the call is at DISPATCH_LEVEL
Return Value:
