Hello Atul,
One quick note before you start replying: please fix your email
client, as you've been told before. Quoting has to add a quoting
marker (the '>' character) at the beginning of the line, otherwise
it's impossible to separate your reply from the email you're quoting.

Why 32 characters?

Don't break bisection. The code has to compile after every
patch. These are already defined in net/tls/tls_main.c.

I could find only one use of it, in chtls_register_dev. Is this
actually needed?

I was trying to figure out what this did, because the name is really
not explicit, and the comment doesn't make sense, but noticed it's
never actually called.

I think you should add a kerneldoc comment, like all the ndo_*
methods have.

Prototype without implementation, please don't do that. This happens
because you split your patchset so that each patch has all the changes
for exactly one file.
