The changes were not localized.  If you want to try to do it manually,
look for the MFC that _included_ this one to
sys/net80211/ieee80211_output.c:

revision 1.26.2.7
date: 2006/03/23 23:28:43;  author: sam;  state: Exp;  lines: +15 -0
MFC 1.40: when doing s/w crypto make sure work is done w/ a writable
    mbuf chain; this corrects problems with drivers that rely on the
    host to do crypto

Probably safest to just update.
