[dpdk-dev] [PATCH] net/cxgbe: fix build with clang 3.4.2

[Ferruh Yigit]

Build error:
.../drivers/net/cxgbe/cxgbe_flow.c:315:2:
    error: implicit truncation from 'int' to bitfield changes value
    from -1 to 7 [-Werror,-Wbitfield-constant-conversion]
        CXGBE_FILL_FS(adap->pf, ~0, pf);
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.../drivers/net/cxgbe/cxgbe_flow.c:25:2:
    note: expanded from macro 'CXGBE_FILL_FS'
        __CXGBE_FILL_FS(v, m, fs, elem, e)
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.../drivers/net/cxgbe/cxgbe_flow.c:15:18: note:
    expanded from macro '__CXGBE_FILL_FS'
        (fs)->mask.elem = (__m); \
                        ^ ~~~~~
Commit in fixes line changes 'PF_BITWIDTH' to '3', which makes 'fs->pf'
bitfield size '3', changing '~0' to '0x7' to prevent truncation in
assignment.

Fixes: dcd456abe46f ("net/cxgbe: support flow API for matching all packets on PF")
