>Description:
The problem is described there:
https://forums.freebsd.org/viewtopic.php?f=32&t=22664&p=248509#p248509. I don't
know if I can use formating here. The answer on forum sugessts filling bug
report, so I've done it.
I've installed FreeBSD 10.0 RELEASE amd64 on new machine: MSI B85M-G43
(MS-7823).
With the following line in rc.conf:
ifconfig_re0="DHCP"
the Realtek NIC was detected and re(4) driver was initialized but the card
can't get IP configuration from DHCP. After boot I can see in ifconfig re0:
re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=8209b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_MAGIC,LINKSTATE>
ether 44:8a:5b:26:cc:ae
nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
media: Ethernet autoselect (1000baseT <full-duplex,master>)
status: active
The card doesn't have IP and doesn't work. I've tried set IP manually but it
didn't help. After reading the posts in mentioned topic I've tried some
options. I've logged to the system and make the command ifconfig re0 tso and
the card gets IP in few seconds and everything worked fine. So I've changed
rc.conf to:
ifconfig_re0="DHCP tso"
But it didn't help. And I've noticed that any change in one of the 3 parameters
suggested on forum to turn off earlier: tso, rxcsum, txcsum changed after login
makes the NIC working: ifconfig re0 -rxcsum or ifconfig re0 -txcsum helps too.
It could be also -rxcsum inf rc.conf and ifconfig re0 rxcsum after login. And
so on...
pciconf says:

ecap 0003[160] = Serial 1 01000000684ce000
ecap 0018[170] = LTR 1
So I made a little workaround putting to /etc/rc.local line:
/sbin/ifconfig re0 tso
And I still have problems on start with the initial communication with DHCP but
the interface wakes up after rc.local file is processed and seems to work
properly afterwards.
The rc.conf has only:
ifconfig_re0="DHCP"
How to make it better? Is there a problem with driver initialization?
PS. I've had the same problem while trying to install. The system was installed
using USB->Ethernet adapter.
>How-To-Repeat:
Boot the system from CD on the MSI B85M-G43 (MS-7823) motherboard...
>Fix:
Change one of the tso, rxcsum and txcsum parameters for the re0 interface after
booting. Maybe any change of the possible interface parameters?
