I've tested your new patch on hp proliant dl145g2 server with bcm5721 on board
chips:
bge1: <Broadcom BCM5721 Gigabit Ethernet, ASIC rev. 0x4101> mem
0xca100000-0xca10ffff irq 19 at device 0.0 on pci3
It does work but i've found some problems:
minor ones:
1) IPMI stop working for a few seconds while ifconfig bge1 up/down or driver
initialization (perhaps this happens when bge_reset() is called)
2) IPMI interface (bound to brgphy1) is unreachable from bge1 itself. I guess
it's due to simplex nature of bge. I'm not sure this can be fixed.
major one:
Driver is unable to detect link loss. Problematic code is in bge_tick_locked:
/* Don't mess with the PHY in IPMI/ASF mode */
if (!((sc->bge_asf_mode & ASF_STACKUP) && (sc->bge_link)))
mii_tick(mii);
what purpose of this check? mii_tick() call is necessary for updating phy's
link status.
