Modified Files:
        src/sys/dev/ic: gem.c

Log Message:
gem_start() pads a Tx packet to the minimum ethernet frame length
by adding a segment to the Tx chain.  That entails using one more
descriptor.  It did not synchronize the last descriptor.

In gem_start(), clarify and repair DMA synchronization of the Tx
descriptors.  Sync them all.
