Subject: mbuf: add C++ include guard for dynamic fields header
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=397fb6a8d96cf06fc83bd87cadf46d2226fc42ed;p=dpdk.git

mbuf: add C++ include guard for dynamic fields header

The header was missing the extern "C" directive which causes name
mangling of functions by C++ compilers, leading to linker errors
complaining of undefined references to these functions.

Fixes: 4958ca3a443a ("mbuf: support dynamic fields and flags")
