Hmmm, most (if not all) of those you get using netlink, like so for
example:
ip -s -s link show dev eth0
But I see the incentive to add those to ethtool as well.
Yes, I think you can get everything out of netlink..but I find
the ethtool API much easier to use...
I envision one tool to configure network related things through all OSI
layers one day ;). The netlink API is not simple at first sight, however
offers much benefit in long terms, I believe.
+ * set_rx_all: Set or clear IFF_ACCEPT_ALL_FRAMES, see if.h
+ * get_rx_all: Return 1 if set, 0 if not.
+ * set_save_fcs: Set or clear IFF_SAVE_FCS, see if.h
+ * get_save_fcs: Return 1 if set, 0 if not.
Something we would like to have in the standard kernel?
I'd love to see them in the kernel..I have cooresponding patches
for e100 and e1000 to support these features as well. However,
the e1000 maintainers were not interested last I checked...
I reckon we have new e1000 maintainers :). Is a 2.6.x version ready?
On the longer run, well, the IFF_ACCEPT_ALL_FRAMES to me right now is
more of academic (pktgen et al) value and regarding IFF_SAVE_FCS I'm not
sure how people would use it. I don't see how not having
IFF_ACCEPT_ALL_FRAMES would reap VLAN/priority information? Wouldn't
this be a bug in tcpdump? Also how does the frame accounting work using
this flag? Bad frames are still incremented in the stats, despite the
kernel handling those frames.
Regarding IFF_SAVE_FCS I could see a problem with handling the skb for
NICs that do no have this flag set. It would break horribly or you would
need to invent IFF_SEND_ALL_FRAMES.
Slightely OT: What's the status of your VLAN MAC work? Is this for
submission as well?
Thanks for this patch, I wonder if this should be integrated into
ethtool per default?
Again..I'd love to see it in....
Meanwhile I've found your work on your OSS part of candelatech. Very
interesting to me.
Cheers,
