sys/dev/xen/netfront/netfront.c:
o Implement netfront_suspend(), a specialized suspend
handler for the netfront driver. This routine simply
disables the carrier so the driver is idle during
system suspend processing.
o Fix a leak when re-initializing LRO during a link reset.
o In netif_release_tx_bufs(), when cleaning up the grant
references for our TX ring, use gnttab_end_foreign_access_ref
instead of attempting to grant the page again.
o In netif_release_tx_bufs(), we do not track mbufs associated
with mbuf chains, but instead just free each mbuf directly.
Use m_free(), not m_freem(), to avoid double frees of mbufs.
o Refactor some code to enhance clarity.
