Zeeb <bz@FreeBSD.org> AuthorDate: 2023-10-06 10:38:22 +0000 Commit: Bjoern A. Zeeb <bz@FreeBSD.org> CommitDate: 2023-10-06 10:50:06 +0000 net80211: pass __func__, __LINE__ also to ieee80211_alloc_node() Pass caller information to ieee80211_alloc_node() so that in case IEEE80211_DEBUG_REFCNT is compiled in we can (better) track references, in this case the initial ieee80211_node_initref().
