Subject: pim_mroute.h has a different version of code than linux/mroute.h provides
X-Git-Tag: frr-2.0-rc1~864
X-Git-Url: https://git.puffer.fish/?a=commitdiff_plain;h=a724477d97709001bce8b004632d9e1e5adb36be;p=matthieu%2Ffrr.git

pim_mroute.h has a different version of code than linux/mroute.h provides

linux/mroutes.h and pim_mroute.h both have copies of the same structures.
This is causing failures in setsockopt(..., MRT_ADD_MFC,...) because
of data structure incompatibilities between the kernel and what
pim_mroute.h was providing.  Modify the code to check for mroute.h
and include it if necessary.  I did not modify the non linux/mroute.h
path because I do not have other systems to test on easily.
