Maximum number of packets taken from all interfaces in one polling cycle (NAPI
poll). In one polling cycle interfaces which are registered to polling are
probed in a round-robin manner. The limit of packets in one such probe can be
set per-device via sysfs class/net/<device>/weight .

This is the full-colour version of the currently unofficial Linux logo
("currently unofficial" just means that there has been no paperwork and
that I have not really announced it yet). It was created by Larry Ewing,
and is freely usable as long as you acknowledge Larry as the original
artist.
Note that there are black-and-white versions of this available that
scale down to smaller sizes and are better for letterheads or whatever
you want to use it for: for the full range of logos take a look at
Larry's web-page:

Tux is taking a three month sabbatical to work as a barber, so Tuz is
standing in. He's taken pains to ensure you'll hardly notice.

** 5/2/94 Roman Hodek:
** Added bi_atari part of the machine dependent union bi_un; for now it
** contains just a model field to distinguish between TT and Falcon.
** 26/7/96 Roman Zippel:
** Renamed to setup.h; added some useful macros to allow gcc some
** optimizations if possible.
** 5/10/96 Geert Uytterhoeven:
** Redesign of the boot information structure; moved boot information
** structure to bootinfo.h
