to each port once every 30 seconds.
* Additionally fixes the on-ward passing of LLDP frames through
the switch
The ports on the case are marked 1-8 so this should reflect that
rather than being 0-based
We can send the hostname as well, this can be dynamically allocated
Let's send the model as the system description as well
igmp_setup(), which `igmp off` also calls, enabled the lookup of IPv4
multicast in the L2 table. Groups learned while IGMP was on therefore
kept going only to the ports that had reported them, and with reports
no longer trapped nothing updated those entries until a reboot.
The lookup is now enabled in igmp_enable() and disabled in igmp_setup(),
so with IGMP off all IP multicast is flooded again.
The switch keeps a count of the dynamic L2 entries learned on every
port in L2_LRN_PORT_CONSTRT_CNT (0x53ac + 4 * port, 13 bits). `stat`
prints it in a new MACs column and /status.json carries it as "macs".
On a SWTGW218AS the count matched the L2 table port by port, static
entries are not included, and taking a port down drops it to 0.
The switch keeps flooding 224.0.0.0/24 with IGMP on, but a report for a
group in that block still made an entry for it, and the entry limited
the group to the ports that reported it. A host announcing mDNS on
224.0.0.251 thereby cut mDNS off from every other port. Such reports
are now ignored, as RFC 4541 asks.
leds_dump() printed the pin mux, the LED enables and every LED set on each
boot, from BANK2. It now lives in its own file in BANK3, where there is
room, and runs only on the new "leds" command, next to gpio and sds, so it
stays at hand for bringing up a new board without costing BANK2 or boot
output.
A matrix of the ports, one row per ingress port, showing which ports a
frame entering there may leave through. The port number of a row turns
red when the port is not fully open, and the cell for the port itself is
marked since it is always allowed. Apply sends one "isolate" command per
changed row, and Allow all ticks the whole matrix.
The switch side is a new /isolation.json, which reports each port's
allowance mask read back from the hardware. The page is an Isolation
section of the single-page UI.
494320b removed strcpy() from rtl837x_flash.c but left its declaration
in rtl837x_common.h. Since then the linker has taken strcpy from the
SDCC library instead, which expects the destination as a generic pointer
in DPL, DPH and B. The callers pass an __xdata pointer and leave B as it
is, so the copy lands wherever B happens to point. boot.c only gets away
with it because B is zero there; a call with B set, as from the ChaCha20
test in #207, writes into internal RAM and stops the 8051.
With several switches open, every tab was called "Switch". The
dashboard tab now shows the hostname, and the login page shows the
hostname seen at the last login on that address (kept in localStorage,
which is per switch), or the address itself before the first login.

The firmware page accepted any valid image, also one built for a
different board whose SFP, LED and button pins differ. Every image
carries its machine name as a NUL-terminated string, the same one the
switch reports as hw_ver; when the selected image lacks it, the page
now warns below the check result and in the confirmation dialog. The
upload stays possible on purpose.

The V3.2 board has the same component placement as V3.1 and works with
its machine definition: RJ45 links at 2.5G, LEDs, SFP detection with DOM
readings at 10G, factory MAC at 0x1FC000 and the reset button. The new
target only reports "V3.2" as the machine name.
Installed from the original firmware V100.9.25 through its web
interface with the OEM installer image. Reading the flash in-circuit with
a SOIC-8 clip gave the chip ID EF FF FF, as on a V3.1 board.

Follow-up to #494. Storm control (#455) was merged after it and brings
three objects in code space without const: the extern declaration of
machine in rtl837x_storm.c and the name tables storm_types and
storm_names. SDCC 4.6.0 reports them as warnings 356 and 357, which
fail the build with CI=1 (--Werror). SDCC 4.5, which the CI uses, does
not report them.
The declarations now take the form used in the rest of the tree, as in
mime_strings in httpd.c. The images for KP_9000_6XHML_X2 and
KP_9000_9XHML_X_V3_1 are byte-identical before and after.
Adds a German dictionary to LANG in app.js (all 317 keys, placeholders
unchanged), the language selector entry in index.html and the login
strings in login.html. Uses Swiss spelling (ss instead of ß), which
reads correctly for all German speakers.
Checked against a mock of the httpd endpoints: every section renders
with the German strings; no layout changes compared to English.

Only frames to 01:00:5e:00:00:16 reached the IGMP handler, so v1/v2
reports, which go to the group address, were never seen. The handler
also took the group from the first v3 group record for every type.
Pass all IPv4 multicast to the handler, which takes the IGMP header
from the IP header length, the group from the IGMP header for v1/v2
reports and v2 leaves and from the first group record for v3, and
returns 0 for anything that is not IGMP so it goes on to the IP stack.
The message and record types have names now.
Storm control used meters 0 to 39, the same meters the ACL hands out,
so a storm limit and an acl meter could overwrite each other. It now
uses 24 + port * 4 + type, meters 24 to 63.
parse_storm() is no longer reentrant and uses plain locals, looks the
type up in a while loop and returns straight from the one-line cases.
storm_show() uses plain locals too.
The documentation says how IGMP decides between mcast and umcast, how
to get from a meter index to its limit, where the IFG bit of a meter
is, and what an ingress bandwidth limit on the same port does to the
storm limit.
The switch has no battery backed clock, only a seconds counter that starts
at zero on every boot. An SNTP client keeps UTC as the time of the last
answer plus the seconds counted since: "ntp server <name|ip>", "ntp interval
<minutes>", "ntp timezone <+hh:mm>", "ntp dst off|eu|us", "ntp on|off",
"ntp" and "time". A server given by name goes through the DNS resolver, an
answer from an unsynchronised server is ignored, and a failed attempt is
repeated after 30 seconds.
The local time adds the time zone offset and, while the European or United
States rule says so, one hour. The date is split with a shift and subtract
division and a walk over the years, so no 32-bit division from the library
ends up in the common area.
The System page gets the NTP settings and shows the local time.
