Hello List!

I am having difficulties in getting a nic to work in a new server.

bge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
capabilities=3f80<TSO4,IP4CSUM_Rx,IP4CSUM_Tx,TCP4CSUM_Rx,TCP4CSUM_Tx>
capabilities=3f80<UDP4CSUM_Rx,UDP4CSUM_Tx>
enabled=0
ec_capabilities=7<VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU>
ec_enabled=0
address: 9c:b6:54:97:dd:55
media: Ethernet autoselect (1000baseSX full-duplex)
status: no carrier
inet 8.9.1.6 netmask 0xffffff00 broadcast 8.9.1.255
inet6 fe80::9eb6:54ff:fe97:dd55%bge0 prefixlen 64 scopeid 0x1

I can't get a link.

Its a bcm5720 chip but internal not as an adapter.
01:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5720
Gigabit Ethernet PCIe

Hardware wise, this is the server:
http://h18000.www1.hp.com/products/quickspecs/14737_na/14737_na.pdf
in this Chassi:
http://h10032.www1.hp.com/ctg/Manual/c03728406.pdf

Linux wise:

Settings for eth0:
Supported ports: [ FIBRE ]
Supported link modes: 1000baseT/Half 1000baseT/Full
Supported pause frame use: No
Supports auto-negotiation: Yes
Advertised link modes: 1000baseT/Half 1000baseT/Full
Advertised pause frame use: Symmetric
Advertised auto-negotiation: Yes
Speed: 1000Mb/s
Duplex: Full
Port: FIBRE
PHYAD: 8
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: g
Wake-on: g
Link detected: yes

driver is: tg3

Linux connects via 5718S PHY

tg3 0000:01:00.0 eth0: Tigon3 [partno(N/A) rev 5720000]
(PCI Express) MAC address 9c:b6:54:97:dd:55
tg3 0000:01:00.0 eth0: attached PHY is 5718S
(1000Base-SX Ethernet) (WireSpeed[0], EEE[0])

I also tried FreeBSD 10. Same Problem no carrier.
Then I tried OpenBSD 5.5. It shows status: active, but
autoselect (none). I can't connect.

Then I modified one line of code via msaitoh@

http://svnweb.freebsd.org/base?view=revision&revision=241390

with that change I also get status: active
and brgphy is attaching to bcm5709S phy
but I still have autoselect (none) and
trying to set media type manually results in:
SIOCSIFMEDIA

ifconfig -m bge0 shows:
media none
media 1000baseSX
media 1000baseSX mediaopt full-duplex
media autoselect

Any help is appreciated.

Cheers,
Zafer

Our brgphy()'s SerDes related code was #if 0 ed. For OpenBSD,
the code was enclosed with

if (strncmp(devname, "bnx"))

Perhaps we have to fix this problem first.

I committed a lot of fixes into brgphy(4) and bge(4). Now the
machine works fine with the latest -current.

Thank you for your help!
