The fields I look at most often in the ill are:
ill_name
ill_wq (ill_rq is easy to derive from ill_wq; no need to print both)
ill_dl_up
ill_mactype or ill_type
ill_flags
ill_state_flags
ill_phyint
ill_isv6
ill_refcnt, ill_ire_cnt, ill_nce_cnt, ill_ilm_cnt
ill_ilm_walker_cnt
ill_waiters
ill_ipst
ill_grp
Also, the pointers to the ill_ipif and ill_ilm lists, but some thought
would need to be put into how to display those meaningfully.
For the ipif_t:
name (derived from both the ill name and ipif_id)
ipif_ill pointer
ipif_v6lcl_addr (displayed in a.b.c.d/n notation)
ipif_flags
ipif_state_flags
ipif_addr_ready
ipif_refcnt, ipif_ire_cnt, ipif_ilm_cnt
