i am trying to send an arp request ,
i use SIOCSARP ioctrl , fill the arpreq , it works fine

but now i want to be able to send an arp request with a custom vlan ,
i tried to use setsockopt , as
"wr_net_stack_vxworks_6_programmers_guide_vol3_6.6" advise
but without luck

someone know a solution please , without adding an interface with vlan
egress taging ?
thanks in advance
