m_freem()

m_freem() would be a perfect candidate for an inline function.
(or even macro).
in the case where m is null, no function call would even be made...
The whole function is only 2 lines, and it gets called once for every packet :-)


BUT it's a part of the ABI to have it as a function for RELENG_7 and earlier...
1/ can we change it in -current/RELENG_8
2/ if not is there such a thing as an inline that has a function version too?

(I have vague memories of that being possible...)
