What

  • Syncronise PATH MTU value between EP's

Why ?

  • On clusters where combination Connect-X3/Connect-X4+ are used there could be used incorrect values of PATH MTU values which prevents communication between sych systems

How ?

  • Pack MTU value for HCA where non 4096 MTU are used

cherry picked from #6216 as a single commit

- pack MTU value for HCA where non 4096 MTU are used
- added gtest for non-unified MTU

No need. After merging the commits, were there any conflicts?
