[dpdk-dev] [PATCH v1] net/txgbe: offset needs to be initialised to fix gcc compile error

When DPDK is compiled with gcc 7.5 with the optimization level set to 1
gcc sees the offset variable in txgbe_ethdev.c as possibly being
uninitialised. To correct this error offset has been initialised to 0 in
txgbe_ethdev.c
