shortest possible chain of mbufs of m_defrag(9). What we want is
chains of mbufs that can be safely stored to a Tx descriptor which
can have up to STGE_MAXTXSEGS mbufs. The ethernet controller does
not need to align Tx buffers on 32bit boundary. So the use of
m_defrag(9) was waste of time.

- Turn on WOL bits in suspend/shutdown method.
- WOL is disabled in resume routine as WOL can interfere normal
Rx operation.
- Move stge_reset() to stge_init_locked() as resetting hardware
clears configured Rx information which in turn results in
non-working Rx module after suspend/shutdown operation.

While I'm here move MAC control settings to stge_link_task, a task
queue which handles link state and duplex/flow controls.

If these drivers are setting M_VLANTAG because they are stripping the
layer 2 802.1Q headers, then they need to be re-inserting them so any
bpf(4) peers can properly decode them.
It should be noted that this is compiled tested only.

bus_setup_intr()
o add an int return code to all fast handlers
o retire INTR_FAST/IH_FAST

sparc64 GENERIC and the sound device drivers known working on sparc64
to use bus_get_dma_tag() to obtain the parent DMA tag so we can get rid
of the sparc64_root_dma_tag kludge eventually. Except for ath(4), sk(4),
stge(4) and ti(4) these changes are runtime tested (unless I booted up
the wrong kernels again...).

m_pkthdr.ether_vlan. The presence of the M_VLANTAG flag on the mbuf
signifies the presence and validity of its content.
Drivers that support hardware VLAN tag stripping fill in the received
VLAN tag (containing both vlan and priority information) into the
ether_vtag mbuf packet header field:
m->m_pkthdr.ether_vtag = vlan_id; /* ntohs()? */
m->m_flags |= M_VLANTAG;
to mark the packet m with the specified VLAN tag.
On output the driver should check the mbuf for the M_VLANTAG flag to
see if a VLAN tag is present and valid:
if (m->m_flags & M_VLANTAG) {
... = m->m_pkthdr.ether_vtag; /* htons()? */
... pass tag to hardware ...
}
VLAN tags are stored in host byte order. Byte swapping may be necessary.
(Note: This driver conversion was mechanic and did not add or remove any
byte swapping in the drivers.)
Remove zone_mtag_vlan UMA zone and MTAG_VLAN definition. No more tag
memory allocation have to be done.

controller ported from NetBSD. It supports the following Gigabit
Ethernet adapters.
o Antares Microsystems Gigabit Ethernet
o ASUS NX1101 Gigabit Ethernet
o D-Link DL-4000 Gigabit Ethernet
o IC Plus IP1000A Gigabit Ethernet
o Sundance ST-2021 Gigabit Ethernet
o Sundance ST-2023 Gigabit Ethernet
o Sundance TC9021 Gigabit Ethernet
o Tamarack TC9021 Gigabit Ethernet
The IP1000A Gigabit Ethernet is also found on some motherboards
(LOM) from ABIT.
Unlike NetBSD stge(4) it does not require promiscuous mode operation
to revice packet and it supports all hardware features(TCP/UDP/IP
checksum offload, VLAN tag stripping/insertion features and JUMBO
frame) and polling(4).
Due to lack of hardware, hardwares that have TBI trantransceivers
were not tested at all.
Special thanks to wpaul who provided valauble datasheet for the
controller and helped to debug jumbo frame related issues. Whitout
his datasheet I would have spent many hours to debug this chip.
Tested on: i386, sparc64
