i40e_rxtx_vec_sse.c fails to compile with below configuration:
- #define RTE_LIBRTE_I40E_16BYTE_RX_DESC 1 in config/rte_config.h
- cpu=core-axv-i
- gcc which supports -mavx2 (e.g. gcc 4.8.5)
This is because commit 0604b1f2208f ("net/i40e: fix crash in AVX512")
added i40e_rxq_rearm_common() to i40e_rxtx_vec_common.h which is
included by i40e_rxtx_vec_sse.c.
This function is enabled for compilation if CC_AVX2_SUPPORT is defined.
As per drivers/net/i40e/meson.build, CC_AVX2_SUPPORT is defined when
either CPU supports __AVX2__ or compiler supports -mavx2 option.
So for given configuration, CC_AVX2_SUPPORT gets defined but we
don't pass -mavx2 explicitly to gcc while compiling i40e_rxtx_vec_sse.c.
Hence it fails due to avx2 specific code from i40e_rxq_rearm_command().
This patch tries to fix the compilation by moving
i40e_rxq_rearm_common() to a new header file which will only be
included by i40e_rxtx_vec_avx2.c and i40e_rxtx_vec_avx512.c.
Fixes: 0604b1f2208f ("net/i40e: fix crash in AVX512")
