Subject: net: rename u16 to fix shadowed declaration
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=68248ad1b9a8a5e84611346b699dd5d4f1bbe37d;p=dpdk.git

net: rename u16 to fix shadowed declaration

This patch renames u16 to u16_buf. u16 as a variable name causes a shadowed
declaration warning if, for example, the application also typedefs u16
(e.g. by including a header containing "typedef unsigned short u16") and
the application is built with -Wshadow.
