`ip addr` when run under qemu-user-riscv64, fails. This likely is
due to qemu-5.1 not doing translation of RTM_GETNSID calls.

There are 2 separate, but related, issues.

A number of static variables were not modified. Make them const to allow
the compiler to put them in read-only memory. In order to do so,
constify a couple of input pointers as well as some local pointers.
This moves about 35Kb to read-only memory as seen by the output of the
size command.

Some of the IS2 IP4_TCP_UDP keys are not correct, like L4_DPORT,
L4_SPORT and other L4 keys. This prevents offloaded tc-flower rules from
matching on src_port and dst_port for TCP and UDP packets.

drivers/ne
All 3 switch drivers from the Ocelot family have the same bug in the
VCAP IS2 key offsets, which is that some keys are in the incorrect
order.
Vladimir Oltean (2):
net: dsa: seville: fix some key offsets for IP4_TCP_UDP VCAP IS2
entries
net: mscc: ocelot: fix some key offsets for IP4_TCP_U
The IS2 IP4_TCP_UDP key offsets do not correspond to the VSC7514
datasheet. Whether they work or not is unknown to me. On VSC9959 and
VSC9953, with the same mistake and same discrepancy from the
documentation, tc-flower src_port and dst_port rules did not work, so I
am assuming the same is true her
Since these were copied from the Felix VCAP IS2 code, and only the
offsets were adjusted, the order of the bit fields is still wrong.
Fix it.
