The network agent's polling mode: refused by all three, and not about the switch's bus, 2026-10-25

Discovery 25 of the discoveries. The network agent on the coprocessor takes a message called SET_POLLING_MODE (0x44) that nothing sends, and the agent's own reads of the switch's bus spoil os-xgs-npu's there (639) - so the message was taken for a way to change how the agent polls, and perhaps a cure. Read in the vendor's GPL release and asked of all three coprocessors - the second XGS 3300 on SFOS 22's software, the first on SFOS 23's, the XGS 136 on SFOS 21's - with octep.ko 6cde3fde and npuep.ko 590205fb (images/deploy/lab-pollmode-report.sh).
