SubjectRe: [DOCUMENTATION PATCH] Missing net sysctls, some fixed, rest flagged

Looks fine, I applied it with some minor changes as follows:

# [NET]: Update some sysctl documentation.
#
# I ran the following (crappy) script:
# ...
# In /proc/sys/ and found a host of undocumented sysctls. This patch documents
# a number of them, and at least mentions the rest as 'TODO'. Please verify my
# code-inspired documentation before applying!
