the 12.4.11 firmware with a few changes to the link handling code merged
in from the 12.4.13 release. I'm doing this because the 12.4.13 firmware
doesn't seem to handle 10/100 link settings properly on 1000baseT cards.
Note that the revision codes still identify the firmware as 12.4.13
because both ti_fw2.h and ti_fw.h have to have the same revision values,
and I wanted to keep the 12.4.13 firmware for Tigon 1 cards.
It's nice to have firmware source.
cards. This basically involves switching to the 12.4.13 firmware, plus
a couple of minor tweaks to the driver.
Also changed the jumbo buffer allocation scheme just a little to avoid
'failed to allocate jumbo buffer' conditions in certain cases.
bug in the stats accounting (nicSendBDs counter was bogus when TX ring was
configured to be in host memory).
Update if_tireg.h to look for new firmware fix level.
Networks Tigon 1 and Tigon 2 chipsets. There are a _lot_ of OEM'ed
gigabit ethernet adapters out there which use the Alteon chipset so
this driver covers a fair amount of hardware. I know that it works with
the Alteon AceNIC, 3Com 3c985 and Netgear GA620, however it should also
work with the DEC/Compaq EtherWORKS 1000, Silicon Graphics Gigabit
ethernet board, NEC Gigabit Ethernet board and maybe even the IBM and
and Sun boards. The Netgear board is the cheapest (~$350US) but still
yields fairly good performance.
Support is provided for jumbo frames with all adapters (just set the
MTU to something larger than 1500 bytes), as well as hardware multicast
filtering and vlan tagging (in conjunction with the vlan support in
-current, which I should merge into -stable soon). There are some hooks
for checksum offload support, but they're turned off for now since
FreeBSD doesn't have an officially sanctioned way to support checksum
offloading (yet).
I have not added the 'device ti0' entry to GENERIC since the driver
with all the firmware compiled in is quite large, and it doesn't really
fit into the category of generic hardware.
