I was observing this strange problem today while verifying performance of Sequoia board.

Initial conditions:
1) 2.6.12-rc3_L002 kernel from PMCS ftp, compiled for 32bit mode
2) bridge code is compiled into kernel
3) four 100Mbps ethernet devices and one onboard Gigabit link are joined into bridge using bridge-utils-1.1 4) I connected board gigabit link to SmartBit Gb interface and four 100mbps links to SmartBit FastEthernet interfaces

But 'brctl showmacs br0' shows only fast ethernet links being learned, but never gigabit. We have suspicion that Titan driver affects this somehow.

Does anybody have any idea about it or ran into this before?

Thanks in advance!

With best regards, Roman Mashak. E-mail:
