[forcedeth] Increase TX ring size to prevent dropped packets
Commit 947976d ("[netdevice] Do not force a poll on net_tx()")
requires network devices to have TX rings that are sufficiently large
to allow a transmitted response to all packets received during a
single poll.

[forcedeth] Replace driver with native iPXE driver
This patch adds a native iPXE forcedeth driver and removes the legacy
Etherboot forcedeth driver. It supports 40 different chips, compared
to the original 14.
It has been tested on a NIC with an CK804 Ethernet Controller, and the
results of downloading 5 100mb images in a row have been:
12/11/11/11/11 seconds; booting DSL using pxelinux also succeeded. The
driver has also been tested by chaining undionly.kpxe and it worked.
