period before updating to the new driver API (which can cope with
having TX packets in progress).

(This actually matters once you try using TCP, because you *will*
receive full-sized frames.)

Update rtl8139 driver to instantiate an SPI interface with a three-wire
device attached.

Print warning message at probe time.

not-yet-updated drivers to at least function.

generic three-wire serial device support for EEPROM access.

Generic PCI code now handles 64-bit BARs correctly when setting
"membase"; drivers should need to call pci_bar_start() only if they want
to use BARs other than the first memory or I/O BAR.

Split rarely-used PCI functions out into pciextra.c.

Core PCI code is now 662 bytes (down from 1308 bytes in Etherboot 5.4).
284 bytes of this saving comes from the pci/pciextra split.

Cosmetic changes to lots of drivers (e.g. vendor_id->vendor in order to
match the names used in Linux).

Tie into existing driver API; we'll fix that up soon.

even when __atribute__ (( unused )) is correctly set...

I want to get to the point where any header in include/ reflects a
standard user-level header (e.g. a POSIX header), while everything that's
specific to gPXE lives in include/gpxe/.  Headers that reflect a Linux
header (e.g. if_ether.h) should also be in include/gpxe/, with the same
name as the Linux header and, preferably, the same names used for the
definitions.

implementation allows for only one, and does so without compromising on
the efficiency of static allocation).

Link-layer protocols are cleanly separated from the device drivers.

Network-layer protocols are cleanly separated from individual network
devices.

Link-layer and network-layer protocols are cleanly separated from each
other.

No code changes apart from commenting one unused function out.

symbol.

Moved transmit before poll, since typically transmit will be implemented first.

Use shared symbols.
Correct other symbol violations.
