What does proto signifies over here, I was following this
https://github.com/xdp-project/xdp-tutorial/tree/master/tracing03-xdp-debug-print Can anyone explain what proto means in this context?
$ sudo ./trace_read
src: 5a:b3:63:62:de:d7 dst: 3a:b:b:8e:5e:6a proto: 56710
src: 5a:b3:63:62:de:d7 dst: 3a:b:b:8e:5e:6a proto: 56710
src: 5a:b3:63:62:de:d7 dst: 3a:b:b:8e:5e:6a proto: 56710
>Solution :
In this context, given it seems to be displaying L2 information, proto is the Ethertype. It indicates the protocol of the next header (L3).
56710 is 0xDD86 in hexadecimal, which corresponds to the Ethertype of IPv6.
