Description Massimo 2013-01-31 14:30:02 UTC
I'm using Freebsd on Freenas 8.3  HW is based on ATOM E6xx series , chipset EG20T PCH , but I have problems on network , seems that system doesn't see the ethernet port, verifying seems that freebsd 8.3 doesn't support this chipset , could you let me know if there is a workaround or there is the possibility to have the driver or load driver or rev.9.0 support also this chipset ,or there is a kind of patch for it.
Below the statement of the system.

Responsible Changed
From-To: freebsd-bugs->freebsd-net

Although this is system-specific, I'll take a chance on assigning this 
to freebsd-net in case someone knows of a way to convince an existing 
driver to see this chip.
Comment 2 marius 2013-02-01 17:21:34 UTC
FreeBSD simply has no driver supporting this MAC, yet, i.e. a counterpart
to the Linux pch_gbe.
Comment 3 Nick Hibma freebsd_committer freebsd_triage 2014-06-13 19:22:06 UTC
We've successfully run FBSD10-STABLE on a EG20T chipset platform and used its networking as well. You might want to try again.

Really?  Which device driver you use?
Marius is right, there's no FreeBSD support for this device.
Comment 5 Nick Hibma freebsd_committer freebsd_triage 2014-06-17 09:13:54 UTC
My bad: We had some problems with this EG20T platform and I thought we resolved them all. We managed to get the 82574L (if_em) based adapters to work (invalid EEPROM checksum). I hadn't noticed the

which isn't wired up at all externally. Thanks, Kevin, for correcting me! Reopened.

batch change:

For bugs that match the following
-  Status Is In progress 
AND
- Untouched since 2018-01-01.
AND
- Affects Base System OR Documentation

DO:

Reset to open status.


Note:
I did a quick pass but if you are getting this email it might be worthwhile to double check to see if this bug ought to be closed.
Comment 7 Sean Bruno freebsd_committer freebsd_triage 2018-05-29 15:28:17 UTC
The EG20T seems to be a special case Intel Gigabit controller that requires special support.  A quick scan of the internet, linux and bsd trees shows that a lot more work would be required to get this functional.
