fix(talos): set chronos NIC ring buffers to 4096

MaudeBot · kiliantyler · MaudeBot · commit 8d05a8048faa · 2026-03-23T17:27:42.000-04:00
Intel I219-V e1000e default RX ring is 256 descriptors. During traffic
bursts (Ceph replication + ingress), the ring fills and packets drop.
Max supported is 4096. Applied live via talosctl, persisted in talconfig.
