Chrome sends upload requests using POST with multipart/form-data
content type in multiple packets for the header part of the form-data.
Introduce a TSTATE_MULTIPART for the httpd server states that denotes
that so far only a part of the multipart header has been transmitted.
Once the full header has been transmitted, we change to TSTATE_POST
as for Firefox which sends all the multipart header in one piece.
The main further change required then is to make sure that the parsing
of the initial part of the multipart request is only parsed once and initially
to distinguish between configuration and firmware uploads.
Add support for the ZX310S-4T2XH switch, which is a 4x2.5GBit + 1x10GBit + SFP
device. The device does not have any branding and is sold under different
brand names, in particular by Horaco. There is no branding on either label
nor PCB.
CPU: RTL8372
Flash: 2MByte Winbond W25Q16DV
10GBit PHY: RTL8261BE
UART header present, but solder holes are filled with solder that needs
removal, first, e.g with a 1.2mm drill.
The original firmware uses 57600baud 8N1
Register RTL8373_EEE_CTRL_BASE did not actually exist at 0x606c,
instead RTL837X_EEE_STATUS is actually not only a status, but also
a control register for EEE enable/disable at the MAC.
The defines are not actually register bits, but port EEE settings,
so move them to rtl837x_port.h while adding 5G/10G flags.
This uint8_t field corresponds to the n_sfp field and gives the number
of 10G ports for the machine. The values can be 0, 1, 2 for known machines,
all currently supported machines do not have any 10G ports, so no
need to change any entries in machine.c
Remove the return argument because `err_status` is also reflecting the result.
Fix the error message when too many arguments are found.
refactor `execute_config()`, error out when err_status is not OK.
