[meta-freescale] imx6q: FEC ENET: rcv is not +last

[Prasant J]

Hi All,

I'm using linux-3.0.35 (local version: -2026-geaaf30e ) on my custom
hardware (uses imx6 quad) design based on sabresd platform. I'm using yocto
root filesystem (this is a soft float build).

My custom hardware uses Micrel's Gigabit Ethernet PHY KSZ9021RNI.

On  gigabit network I get kernel messages (on serial console):
FEC ENET: rcv is not +last
and network is very unstable.

On a 100 mbps network, network is very stable and I do not get these
messages.


I read on imxcommunity that this issue is resolved in L3.0.35_4.1.0
release. I tried the kernel from that release (it has patches upto patch
no. 2666) but this issue is still there.


Can someone give me more information about this problem ? Is there a fix
for this solution already?

(I'm aware that the Imx6 is limited to 470 mbps, I read that in Chip
errata.)
