[PATCH mptcp-next 0/4] reflect mptcp_pm_add_addr_signal

[Geliang Tang <geliang.tang@suse.com>]

mptcp_pm_add_addr_signal() has too many parameters right now. This issue
was introduced by me and I promised to fix it last year:

https://patchwork.kernel.org/project/mptcp/patch/f0920ba1126ff81aa1acbff47e805e5573c64abc.1626158123.git.geliangtang@gmail.com/

This patch set reflected this function and dropped the port and echo
parameters.

As defined in $3.4.1:
                       1                   2                   3

  |                Truncated HMAC (8 octets, if E=0)              |
  |                               +-------------------------------+
  |                               |

The echo bit is one of the important properties of a MPTCP address. It
makes sense to put it into struct mptcp_addr_info with others properties
like the address family, the id number and the port number too. So patch
2 added the echo bit in struct mptcp_addr_info. With this change, we can
drop the echo parameter of mptcp_pm_announce_addr too, or even drop the
addr_signal status MPTCP_ADD_ADDR_ECHO later (not finish yet).

Geliang Tang (4):
  mptcp: drop port parameter of mptcp_pm_add_addr_signal
  mptcp: add echo bit in mptcp_addr_info
  mptcp: drop echo parameter of mptcp_pm_add_addr_signal
  mptcp: drop echo parameter of mptcp_pm_announce_addr
