sys/pci if_de.c
Log:
- Use m_defrag() instead of homerolling our own variant
tulip_mbuf_compress(). If we fail to allocate a new mbuf to copy the
data into, put the mbuf back in the driver's send queue so that we can
retry it later rather than throwing the packet away.
- Use m_devget() instead of doing it inline ourselves in the
TULIP_COPY_RXDATA case. If we fail to allocate an mbuf to copy the data
into, don't forget about the original mbuf cluster. The old code would
lose the pointer and leak the cluster in that case. Now it doesn't lose
it but always sticks the original rx buffer back into the receive ring
after trying to copy the data out and send it up the stack. Also, if we
fail to allocate a new mbuf to copy the data into, log an input error.
Also, don't combine the priming case with the received-a-packet case to
make the code flow a bit clearer and easier to follow.
