Hi Experts,

I use qmi_wwan linux kernel driver:
drivers/net/usb/qmi_wwan.c
linux kernel version is 5.10.72

Why after connection wwan0 has ip address, but no MAC address ?

wwan0: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST> mtu 1500
inet 25.119.179.70 netmask 255.255.255.252 destination 25.119.179.70
unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 txqueuelen 1000 (UNSPEC)

TX packets 58 bytes 2536 (2.4 KiB)

Hi @Kaney
Yes, only the IP address assigned by the DHCP server.

Hi Iyman,

After connection wwan0 has ip address, but no MAC address
Is it normal ?

Hi @Kaney
Yes, I think you can check whether it can communicate normally. If it can communicate normally, I think there is nothing wrong with it.
