[dpdk-dev] [PATCH] net/bnxt: fix CLANG compilation error

[Ajit Khaparde <ajit.khaparde@broadcom.com>]

Fix a compilation error seen with CLANG.
The current code causes a typedef redefinition error because
'p__LINE__' is a C11 feature. Fixing it by defining it to something
which is not already defined in the language.

Fixes: 3ca9012a81f9 ("net/bnxt: add initial TruFlow core session open")
