Subject: [PATCH] networkd dhcpv4 logging endian fix
On a big-endian host, systemd-networkd prints out IPv4 network
addresses byte reversed:
Feb 10 16:43:32 hostname systemd-networkd[151]: eth0 : DHCPv4 address 158.1.24.10/16 via 1.1.24.10
The address obtained is 10.24.1.158/16 and the route is
10.24.0.0/16 dev eth0 src 10.24.1.187
The macro ADDRESS_FMT_VAL() unpacks a "struct in_addr" in a
little-endian specific manner.
This patch forces the passed address into host order, then unpacks it.
On an x86 later than i486, compiled with -O2, the only extra overhead
is a single bswap instruction.
