Is that zone assigned to a resource pool, or is it using the

My first guess is that the NICs interrupts are going to a CPU that the
zone is using, and the CPU doesn't have enough power to run the zone's
workload *and* be an effective NIC interrupt handler.
Please run the "intrstat" command as root in the global zone, to
determine which CPU is handling interrupts for that NIC. Also, check
which CPU(s) that zone can use.
Please let us know what you learn from those.
