Slightly out of topic I am not sure why NAPI is used on the transmit side.
Originally NAPI was designed to fix the receive interrupt happening on each
receive frame problem, so on transmit side it is to avoid the transmit
done interrupt on each transmit frame? Typically hardware has a way
to
Currently, we only dump a few selected skb fields in
netdev_rx_csum_fault(). It is not suffient for debugging checksum
fault. This patch introduces skb_dump() which dumps skb mac header,
network header and its whole skb->data too.

It looks safe to me. It's only unsafe if your skb is shared which
from my grepping does not appear to be the case (and it cannot be
shared if you're modifying skb->csum which

in this patch series i'm adding a helper for libbpf which would allow
it to load map-in-map(BPF_MAP_TYPE_ARRAY_OF_MAPS and
BPF_MAP_TYPE_HASH_OF_MAPS).
first patch contains new helper + explains proposed workflow
second patch contains tests which also could be used as example of usage
v4->v5:
-
adding test/example of bpf_map__set_inner_map_fd usage

idea is pretty simple. for specified map (pointed by struct bpf_map)
we would provide descriptor of already loaded map, which is going to be
used as a prototype for inner map. proposed workflow:
1) open bpf's object (bpf_object__open)
2) create bpf's map which is going to be used as a prototype
3)

Break KSZ9477 DSA driver into two files in preparation to add more KSZ
switch drivers.
Add common functions in ksz_common.h so that other KSZ switch drivers
can access code in ksz_common.c.
Add ksz_spi.h for common functions used by KSZ switch SPI drivers.

There are several steps to accomplish this achievement. First is to
