[lwip-users] low_level_output question

Hi,
I'm porting lwip (using an RTOS and the socket API) and I have a question 
regarding the low_level_output function.
If I can't send the pbuf immediately (netif busy), to avoid copying the pbuf, 
I'd like to do the following:
*       Increment the reference count to prevent lwip from re-using or freeing 
the pbuf.
*       Put the pbuf on my output queue and try to send it later.
*       Return ERR_OK.
Later when the netif is not busy...
*       Remove the pbuf from my output queue.
*       Send the pbuf.
*       Free the pbuf.

Will this scheme work with lwip?

Thanks,
John Kennedy
