net: dst: Force 4-byte alignment of dst_metrics ...
[ Upstream commit 258a980d1ec23e2c786e9536a7dd260bea74bae6 ]
When storing a pointer to a dst_metrics structure in dst_entry._metrics,
two flags are added in the least significant bits of the pointer value.
Hence this assumes all pointers to dst_metrics structures have at least
4-byte alignment.
However, on m68k, the minimum alignment of 32-bit values is 2 bytes, not
4 bytes. Hence in some kernel builds, dst_default_metrics may be only
2-byte aligned, leading to obscure boot warnings like:

Fix this by forcing 4-byte alignment of all dst_metrics structures.
