Hash: SHA256

Hello,

A new version, v1.0.20200330, of the backported WireGuard kernel module for
3.10 <= Linux <= 5.5.y has been tagged in the git repository.

== Changes ==

  * queueing: backport skb_reset_redirect change from 5.6
  * version: bump
  
  This release has only one slight change, to put it closer to he 5.6 codebase,
  but its main purpose is to bump us to a 1.0.y version number. Now that
  WireGuard 1.0.0 has been released for Linux 5.6 [1], we can put the same number on
  the backport compat codebase.

This is because the skb_reset_redirect() change from 5.6 got backported 
in 5.5.14 and 5.4.29, so you need the attached patch

Fix skb_reset_redirect() backport version check.

Upstream commit 2c64605b590edadb3fb46d1ec6badb49e940b479 got backported in
stable 5.5.14 and 5.4.29, so we need to adjust the version check.
