"watchdog timeout" a "obsoleted if_watchdog interface"

[Jan Stary]

Konecne jsem se dostal k nasledujicimu problemu:
na mem 7.0-RELEASE-p5 (dmesg dole) mi sitovka vr0
pri vetsim trafficu rika

	vr0: watchdog timeout

a sitovy provoz se meritelne zpomaluje. Zkusil jsem to, co radi
http://lists.freebsd.org/pipermail/freebsd-stable/2006-September/028888.html
tedy zapnout device polling, tzn.

	options DEVICE_POLLING

do jadra a

	ifconfig vr0 ... polling

v nastaveni interfacu. Tim prvni problem skutecne zmizel, tj. sitove
prodlevy a hlaska o "watchdog timeout" zmizely, nicmene zustava mi tato
otazka: (nove) dmesg rika o moji vr0 toto (stare dmesg pokracovalo
sekvenci hlasek "vr0: watchdog timeout"):

vr0: <VIA VT6102 Rhine II 10/100BaseTX> port 0xd400-0xd4ff mem 0xdffffe00-0xdffffeff irq 23 at device 18.0 on pci0
vr0: Quirks: 0x0
miibus0: <MII bus> on vr0
vr0: using obsoleted if_watchdog interface
vr0: Ethernet address: 00:0c:76:55:85:56
vr0: [ITHREAD]

1) Co jsou quirks?

2) Znamena "obsoleted if_watchdog interface", ze zrovna vr driver
   pouziva obsoleted if_watchdog interface, zatimco jine drivery
   pouzivaji if_watchdog intarface, ktery neni obsoleted,
   anebo to znamena, ze if_watchdog interface jako takovy
   je obsoleted? Podle /usr/src/sys/net/if.c, ktere rika

	if (ifp->if_watchdog != NULL)
		if_printf(ifp, "using obsoleted if_watchdog interface\n");

   bych rekl, ze spis to druhe.

3) Jelito skutecne tak, znamena to pro me neco? V krajnim pripade,
   je snad v nejakem ohledu lepsi pouzivat kartu, ktera (resp: jejiz driver)
   nepouziva tento obsoleted interface?
