Bug ID: 221317
Summary: Netmap issue after ixgbe driver update
Product: Base System
Version: 11.1-STABLE
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
After commit r320897 (ixgbe driver update to 3.2.12-k) netmap is not working
well anymore. When ixgbe interface is opened many times it changes the status
to "no carrier" and needs a reboot to work again.
It's quite easy to reproduce the issue, just use two machines with ixgbe driver
sending and receiving packets using pkt-gen. Run pkt-gen many times with option
like -p and -c.
To make sure it was a driver update issue i downgrade it ixgbe driver (version
3.1.13-K) released with FreeBSD-11.1-RELEASE and worked fine.
