firmware 1.50.12, but 2.20.1 and 3.10.4 work. The 1.50.12 card gets
past doing dhclient, but hangs on transmit a little after the ip
address is set. The 1.50.12 card has always been 'cranky' and Bill
Paul's tearing it apart at FreeBSD '99 hasn't helped.
sc_reset and sc_enable are subtlely different things. sc_reset means
exactly "WI_CMD_INI has happened." sc_enabled means "WI_CMD_ENABLE
has been sent to the card without a WI_CMD_DISABLE following." This
is a little different than what they mean on NetBSD (where both of
these concepts are comingled). NetBSD will try to only enable symbol
cards once, while FreeBSD only sends the WI_CMD_INI once.
Also, only try once to reset the card on a symbol.
This makes the lucent cards no worse than before, but apparently not
much better either. I got fewer hangs in my testing than I have in
the past, but I don't know if it is statistically significant or not.
