Fix the bug introduced by a commit:
291a32c7 userspace/wrsw_hal: use get_monotonic_* instead of clock_gettime

get_monotonic_tics() return a value in us resolution, so to get ms it has to be
divided by 1000, not multiplied.

Paul Boven authored 8 years ago and Adam Wujek committed 8 years ago

The SFP documentation "INF-8047.pdf" states:
"The serial interface uses the 2-wire serial CMOS E2PROM protocol defined for
the ATMEL AT24C01A/02/04 family of components."

Upon reading that datasheet, some important details stand out:
1) The eeprom can only write in pages, with pages being 8 or 16 bytes. Assuming
   the smallest device, you can only write 8 bytes at a time. To be safe, I'm
   assuming a pagesize of 8 bytes.

   This explains why we only saw stuff change in the first 8 bytes, I guess.

2) A write needs to be preceded by the byte address which is a single byte for
   these devices, and then up to 8 (or 16) data bytes to be written at that
   location. If there are more bytes, or if the data wraps around the page
   binary, it will still only end up on the page belonging to that first
   address.

3) After writing, you need to poll the eeprom to see if it has finished writing
   the byte. At the moment, I'm not doing that yet, instead I'm doing a 10ms
   wait which seems sufficient.

In shared memory functions take as parameters pinters to structures instead
of void pointers. By this compiler will warn when wrong type of pointer is
passed. For example when pointer to the data in shmem is passed instead of

Keep explicitly lock bit in the sequence variable as a LSB bit.
This solution is backward compatible. The difference is only when shmem is
lock twice. Before it was treated as unlocked, now still as a lock.

Remove excessive locks from the function delete_htab_entry.
Function rtu_fd_commit is always guarded with shmem lock. The function
rtu_fd_commit calls rtu_hw_commit, which calls delete_htab_entry. By this
function wrs_shm_write with a parameter WRS_SHM_WRITE_BEGIN was called twice
before it was called twice with a parameter WRS_SHM_WRITE_END.

PHP code of the web interface was updating values of "upload_max_filesize"
and "post_max_size" in the /etc/php.ini. Besides it is extremely bad idea to
do that, such changes to take place require restart of lighttpd, which was
never performed. Luckily after the update of /etc/php.ini it was also copied
to flash at the location /usr/etc/php.ini. Because of this update via
webinterface worked only when:
--firmware.php was opened via web browser
--restart of a switch was performed
