[PATCH net-next v4 01/15] net: stmmac: rearrange stmmac_tx_info members to pack better

[Russell King (Oracle)]

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
