packet corrupt with awge0
Hi everybody,
on Olimex-lime2 board (Allwinner A20, with awge0 gigabit ethernet), I have some errors on long connections.
Using ssh, it aborts with ‘packet corrupt’.
And if using SSL I’ve:
"SSL error while writing: error:1409E10F:SSL routines:SSL3_WRITE_BYTES:bad length” on client.
"SSL error while reading: error:1408F119:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac” on server.
I see some input/ouput errors on ifconfig:
awge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
media: Ethernet autoselect (1000baseT full-duplex)
input: 129932 packets, 30365771 bytes, 10304 multicasts, 123 errors
output: 104008 packets, 48195670 bytes, 7 multicasts, 3 errors
(netstat output at the end of the mail).
I’ve seen some time ago a discussion about checksum errors on awge, but I remember it have been corrected.
Is someone experiencing the same ? Can anybody help about this issue ?
Thank you :-)
Regards,
jym
