Hi NXP team,
I am working with IMX8MM. Currently I am working to bring up LAN8830 with IMX8mm.
Link update working fine
[ 11.771211] fec 30be0000.ethernet eth0: Link is Up - 1Gbps/Full - flow control off
[ 11.778836] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
Ethtool :
ethtool eth0
Settings for eth0:

run udhcpc to getting IP but did't get IP.
After I applied speed change command
ethtool -s eth0 speed 100
Getting ip and ping running file.
what is problem for 1000Mb/s speed ?
Please help me to solve.
