Don Lewis 4ff4a9bee9 The transmit frame status is stored in the last transmit descriptor for the 
frame, not the first.  It is probably also not safe to free the mbuf chain
as soon as the OWN bit is cleared on the first descriptor since the chip
may not be done copying the frame into the transmit FIFO.  Revert the part of
of busdma conversion (if_dc.c rev 1.115) which changed dc_txeof() to look for
the status in the first descriptor and free the mbuf chain when processing
the first descriptor for the frame, and revert the matching changes elsewhere
in the driver.  This part of the busdma change caused the driver to report
spurious collisions and output errors, even when running in full-duplex mode.
Reverting the mbuf chain handling slightly complicates dc_dma_map_txbuf(),
since it is responsible for setting the OWN bits on the descriptors, but does
not normally have direct access to the mbuf chain.
