Because `cmd` is guaranteed by the compiler to be NULL-terminated, we can make use of that to ensure the loop always ends.
So we don't need to know when the next words starts.
Added new `vlan show` command to dump current VLAN settings.
Supports printing PVID & ingress filtering per port.
Added new `ingress [p]<mode>` command to setup ingress filtering.
Added wrappers for enabling/disabling vlan filtering. Currently
not configurable, but state in console is read via ASIC registers.
Full VLAN dump & web support of new commands will be added later.
We fix a bug in atoi_hex when parsing an unneven number of digits
by rotating the entire number 4 bits right as would have been
done if the number had been preceded by a 0 to make the number
of digits even.
The current code for entering commands via the serial CLI is completely
refactored and moved out of rtlplayground.c into a separate file cmd_edit.c
putting code into BANK2.
The serial ring buffer sbuf[] is now exclusively used for receiving
keys, including escape sequences (DEL will generate a 4-byte escape
sequence). The command is now held in cmd_buffer. This reduces
XMEM use, because the serial buffer can be much smaller.
Supported is only editing the current command line via backspace, del,
cursor left and right.
Because the code cannot distinguish escape sequences which are not yet
complete (because the serial isr has not yet put all characters into
the serial buffer) from the dozens of unsupported ones (F-keys/home,
Page up/down, cursor up/down...) they are ignored and remain in the
serial buffer until the ring-pointer overwrites them. This is standard
behaviour for consoles, which will print out garbage for unsupported
characters. In this implementation, the command line buffer and the
visible command line in the terminal are always synced, so garbage
can be removed again by ediing the line.
The code makes several redundant checks in order to prevent race-conditions
between the serial ISR and the comand-editing code.
