Comment 2 for bug 1882335

We have the original patch applied into ubuntu-focal.

ubuntu-focal$ gitoneline | grep 'ip_idents_reserve'
adb03115f459 <email address hidden> 2016-09-22 02:41:17 -0400 net: get rid of an signed integer overflow in ip_idents_reserve()

and we need to find out if there is an revised patch to fix the overflow.
