Commit Message

eni: Fix AWS ENI allocation exceeding IP limits for smaller instance types

For instance types with ENI IP limits lower than the currently
configured spec.eni.pre-allocate, Node.allocateENI() was attempting to
allocate a number of secondary IPs equal to the ENI IP limit, not
accounting for the primary IP. This change causes it to allocate limit-1
secondary IP addresses instead.

This caused failures using default configuration for node groups in AWS
that used smaller instance sizes. For an instance type such as t3.small
with limit of 4 IPs, an ENI with 5 IPs (1 primary, 4 secondary)  would
be allocated which failed to attach.

Fixes: #9730
