Hello everyone,

I have encountered a problem related to initializing 2 Ethernet interfaces on 
IMXRT1064 and I was wondering if you have any idea where to look for solutions.

Sometimes both interfaces work fine. Sometimes, when initializing the second 
interface with ifconfig followed by ifup, the first one dies about 10 seconds 
later. Sometimes the first one stops responding to ping and the debug output is 
showing me "ipv4_input: WARNING: Not destined for us; not forwardable... 
Dropping!" and "ipv4_input: WARNING: IP packet shorter than length in IP 
header"... Although, I am not very sure if this debug output is related to my 
problem. Maybe it's something else.... I still need to dig deeper into it!

Any suggestions will be greatly appreciated!

Best Regards,
Vadim Yastrebov
