Rearrange the struct stmmac_tx_info members to pack better, essentially by sorting by type size: xsk_meta embeds only a pointer - 32 or 64 bit buf dma address, 32 or 64 bit len normally 32 bit buf_type dependent on arch map_as_page normally 8 bit last_segment normally 8 bit is_jumbo normally 8 bit Signed-off-by: Russell King (Oracle) --- drivers/net/ethernet/stmicro/stmmac/stmmac.h | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/drivers/net/ethernet/stmicro/stmmac/stmmac.h b/drivers/net/ethernet/stmicro/stmmac/stmmac.h index bba9bb9c95bf..b096a9e090e3 100644 --- a/drivers/net/ethernet/stmicro/stmmac/stmmac.h +++ b/drivers/net/ethernet/stmicro/stmmac/stmmac.h @@ -47,13 +47,13 @@ enum stmmac_txbuf_type { }; struct stmmac_tx_info { + struct xsk_tx_metadata_compl xsk_meta; dma_addr_t buf; - bool map_as_page; unsigned len; + enum stmmac_txbuf_type buf_type; + bool map_as_page; bool last_segment; bool is_jumbo; - enum stmmac_txbuf_type buf_type; - struct xsk_tx_metadata_compl xsk_meta; }; #define STMMAC_TBS_AVAIL BIT(0) -- 2.47.3
