ja nemam, ostatni "by mali" mat IPcky z DHCPcka, jedine ze by si niekto
nastavil 127.0.0.1, niesom si isty ci to windoozy dovolia pre eth.
Mozem to blokovat, ale ked som cital o Neighbour table overflow a ludia tam
spominali posahany loopback, napadlo ma ci aj tieto martian pakety nesuvisia
s tym posahanym loopbackom...

vsetky realteky boli 8139 - C alebo D, jedna isla s rtl8139too, ostatne len
s tym driverom zo scyld.com.

Este jedna zaujimava vec - kym tam bol ten realtek (a vypadavalo to), v
logoch sa spominali hlasky typu:

Nov 17 22:52:44 darkstar kernel: eth0: command 0x3002 did not complete!
Status=0xffff
Nov 17 22:52:46 darkstar last message repeated 15 times
Nov 17 22:52:53 darkstar kernel: eth0: transmit timed out, tx_status ff
status ffff.
Nov 17 22:52:53 darkstar kernel:   diagnostics: net ffff media ffff dma
ffffffff.
Nov 17 22:52:53 darkstar kernel: eth0: Transmitter encountered 16 collisions
-- network cable problem?
Nov 17 22:52:53 darkstar kernel: eth0: Interrupt posted but not delivered --
IRQ blocked by another device?

Nov 17 22:52:53 darkstar kernel: eth0: command 0x3002 did not complete!
Status=0xffff
Nov 17 22:52:53 darkstar kernel:   0: @c16a5200  length 8000003e status 0000003e
Nov 17 22:52:53 darkstar kernel:   1: @c16a5240  length 8000003e status 0000003e
Nov 17 22:52:53 darkstar kernel:   2: @c16a5280  length 8000003e status 0000003e
Nov 17 22:52:53 darkstar kernel:   3: @c16a52c0  length 8000003e status 0000003e

kabel je samozrejme vporiadku, skuor ma zarazalo ze eth0 bola 3coma, neviem
ci ju ten realtekovsky ovladac nejak blokoval alebo co. Vtedy to tak po
prenesenych 500-600 mega vypadavalo - 3coma isla vpohode, realtek vypadol
(napr ping vypisoval nieco v style send-to failed - Neighbour table overflow)

no je tam len ta stock 2.4.26stka.
ako zatial to bezi, len neviem dokedy, a ci tieto martian pakety (ktorych
tam je dost vela) nesuvisia s problemami loopbacku, alebo s ovladacmi
sietoviek alebo neviem coho...
a to mrznutie s dvoma 3comami premna tiez ostava zahadou...
