This reduces the number of .js which are pulled by the browser
when loading a http page, which should reduce the loading time.
Also prepare for device-dependent logical to physical port
mappings.
This adds an implementation for trapping IGMP packets to the CPU
which will identify IGMPv1/2/3 packets, but handle only v3.
The implementation then inserts/updates/deletes L3 MC entries
in the L3 lookup table. The entries consist of an Ipv4
Destination IP (the IPv4 MC address), a Source IP (0.0.0.0) and
a Portmask. Note that this implementation is not VLAN aware,
as there is no hardware support in the device.
An alternative strategy is to control switching of the L2-MC packets
in which the IPv4-MC packets are transported (dst-MaC is
01:00:5e:xx:yy:zz, with xx:yy:zz corresponding to bits in the Ipv4-MC
address). This will allow to use VLAN-aware packet switching. While
code support is there for table insert/update/deletes, some further
L2 configuration is missing.
There is no support for IPv6 MC, yet.
Put all the device information in one struct `machine`.
So all the device information is defined in one place.
Also easier to add new devices.
Show device name also on website.
Fix SFP status information, some devices have a different SFP layout.
Reworks GPIO handling
Able to set manual port speed, duplex for the RJ45 ports.
The RTL8272/3 use 2 32 bit registers to indicate the MAC link speed, the
second register is used for ports 8 and 9, where 9 is the CPU port.
Use both registers.
This fixes handling of the SFP ports in the stat command.
The output of the command now is for physical ports, which however are
not shown in sequence.
