Subject: Re: [PATCH 2/2] net: remove old tcp_optlen function

In the only two existing files using the old tcp_optlen() function,
clean up confusing and inconsistent mixing of both byte and word
offsets, and other coding style issues.  Document assumptions.

Quoth David Miller:
    This is transmit, and the packets can only come from the Linux
    TCP stack, not some external entity.

    You're being way too anal here, and adding these checks to
    drivers would be just a lot of rediculious bloat. [sic]

Therefore, there are *no* checks for bad TCP and IP header sizes, nor
any semantic changes.  The drivers should function exactly as existing.

Untested.  No response from testers in 10+ weeks.

Requires:
   net: tcp_header_len_th and tcp_option_len_th
