In few places drop parameter of VLANs in dot-config was descibed that
can take different set of parameters, while the only accepted was y or n.
Now it can be y, yes, 1, n, no, 0. However, the tool (wrs_vlans) can use
only 1 or 0 for "drop" parameter.

Disable the Bad Block Table (BBT) because the BBT uses the 4 last PEBs of
nand flash, which overwrites UBIFS.
BBT was disabled in the old kernel. There is not so much performance penalty
due to that (see the last sentence in the citation below). There is no impact
on the reliability of a flash because this is just a table of bad blocks which
is otherwise recreated in the ram at every boot.

The MTD layer supplies upper layers (including UBI) with information about bad
PEBs. It keeps so-called bad block table in RAM, which is usually 1 bit per PEB.
When the driver initializes, it has to build this table by scanning whole flash
media, which normally includes reading OOB area of 1st NAND page of each PEB.
This takes time and may be improved by using on-flash BBT (bad block table).
In this case the bad PEB map is stored on flash and MTD does not have to do any
scanning. See the NAND_USE_FLASH_BBT constant in the Linux source codes. But
note, bad PEB scanning is usually minor comparing to the UBI scan time, so
on-flash BBT is not probably going to give much.

It happens that headers have different sources: buildroot and our own kernel.
For the standard path we have headers from buildroot which include also
some kernel header. For the kernel, we have direct access to those headers.

this means that we mya have conflict in our user-space programs. This patch
does not solve the problem but it just reduce its effects.

The Linux kernel 3.16.37 does not export, or does not have, anymore some
hardware headers. Here I copy all the values we need.

The real fix should be to create a set of WRS headers with all the symbols
we need so that we do not depend anymore on other projects.
