This is useful if user need to get large netlink message.

tools: ynl: ethtool: use doit instead of dumpit for per-device GET 2026-04-12T18:23:49+00:00 Hangbin Liu liuhangbin@gmail.com 2026-04-08T07:08:50+00:00 1c43d471a513e93b5420d8af5d43afd3a75f95f1 Rename the local helper doit() to do_set() and dumpit() to do_get() to better reflect their purpose. Convert do_get() to use ynl.do() with an explicit device header instead of ynl.dump() followed by client-side filtering. This is more efficient as the kernel only processes and returns data for the requested device, rather than dumping all devices across the netns.
