Hi!

From: Björn Töpel <redacted>

[ Upstream commit 7fd3253a7de6a317a0683f83739479fb880bffc8 ]

The existing busy-polling mode, enabled by the SO_BUSY_POLL socket
option or system-wide using the /proc/sys/net/core/busy_read knob, is
an opportunistic. That means that if the NAPI context is not
Do we need this in -stable? It is rather long at 400 lines, and
introduces new API feature, does not fix a bug.

I can revert it on top of 5.10-stable, so I don't believe we have
bugfix depending on it.

Best regards,
								Pavel
