'nfs mounting problem VFS: Unable to mount root fs via NFS
I am not able to mount nfs, my Parameters are like following, it is from bootlin;
setenv bootargs 'console=ttyS0,115200 root=/dev/nfs rw
nfsroot=192.168.0.1:/nfs,nfsvers=3,tcp
ip=192.168.0.100:::::usb0 g_ether.dev_addr=f8:dc:7a:00:00:02
g_ether.host_addr=f8:dc:7a:00:00:01'
setenv bootcmd 'mmc dev 0; devnum=${mmcdev}; setenv devtype mmc;
mmc rescan; run loadimage; run findfdt; run mmcloados'
When I am on uboot console, I called ifconfig command on host, but I couldn't see the network interface. Is it normal? How can I determine if the mac address is correct?
when I tried to ping, I get "host is not alive" feedback.
Bootlog looks like following;

I created a cfg file and added it to my kernel recipe, configuration is below. But I am still unable to achieve nfs mounting. Any suggestions? Is there a way to make sure, may configuration changes are in the built kernel?
I have put all files, MLO, Uboot, dtb and zImage in Boot partition of the sdcard, is it correct?

CONFIG_USB_MUSB_HDRC=y
CONFIG_USB_MUSB_GADGET=y
CONFIG_USB_MUSB_DSPS=y
CONFIG_NOP_USB_XCEIV=y

Thank you.
