net: x25: Remove unimplemented X.25-over-LLC code stubs
According to the X.25 documentation, there was a plan to implement X.25-over-802.2-LLC. It never finished but left various code stubs in the X.25 code. At this time it is unlikely that it would ever finish so it may be better to remove those code stubs. Also change the documentation to make it clear that this is not a ongoing plan anymore. Change words like "will" to "could", "would", etc. Cc: Martin Schiller <ms@dev.tdt.de> Signed-off-by: Xie He <xie.he.0141@gmail.com> Link: https://lore.kernel.org/r/20201209033346.83742-1-xie.he.0141@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
