Re: NetBSD 9.0 not properly configuring NIC

Hi Masanobu and sorry for the delay. I had issues (again) with the
mailserver.

I did as you suggested, commenting the line

atphy*  at mii? phy ?                   # Attansic/Atheros PHYs

in /usr/src/sys/arch/amd64/conf/GENERIC, recompiled and it works!

Here you can find:
- new dmesg, https://pastebin.com/UyEqRFs7
- new `ifconfig -a', https://pastebin.com/xHq2GZeJ

For me it's ok this way. If there is something else that I can do,
please let me know.

If instead it's ok for you too, could you please include this
modification in the kernel, so that -current and the next versions
already have it?

Thanks to you for the suggestion,

P.S.1

Some considerations/doubts:

- Just out of curiosity, was it possible (as an alternative) to disable
`atphy' with `userconf disable atphy' in boot(8)? I tried it in a VM
with wm(4) NIC, which uses makphy(4): booting with `userconf disable
makphy', ukphy(4) has been used instead of makphy(4) (and it works).

- nfe(4) lists several mii(4) drivers (hope that they can be called this
way): `ciphy', `icsphy', `makphy', `rlphy', but not `atphy'. So, I
wonder: why `atphy' was called?

- I am not sure about this, but according to the motherboard manual

 <https://dlcdnets.asus.com/pub/ASUS/mb/socketAM2/M2N-MX_SE_Plus/E3353_M2N-MX_SE_PLUS.zip>

this NIC should also support 1 Gbps transmission, so I guess 1000baseTX,
but the dmesg lists only 10base* and 100base*.


P.S.2

If anyone is interested, the atphy(4) driver has been excluded from the
kernel as follows. I downloaded the NetBSD sources (kernel, tools,
...) for NetBSD 9.0 release using the procedure in this Chapter:

 <http://www.netbsd.org/docs/guide/en/chap-fetch.html>

with `cvs checkout -r netbsd-9-0-RELEASE -P src'.
Then, as specified in

 <http://www.netbsd.org/docs/guide/en/chap-kernel.html>

I considered the GENERIC kernel configuration file for my architecture
(amd64):

 /usr/src/sys/arch/amd64/conf/GENERIC

I copied it to a new file, MGENERIC and looked for `atphy' inside the
file. The only line with this name is the one mentioned above:

 atphy*  at mii? phy ?                   # Attansic/Atheros PHYs

I commented it, and then compiled the kernel using the new configuration
file:

 ./build.sh -j 3 -U tools kernel=MGENERIC

(`-j' is related to the number of threads, it may be 50 % higher than the
number of cores, which in my case is 2).

Then, I installed and used the new kernel as instructed in par. 32.6 of the
above chapter page.

This same procedure can be followed to remove/tune any other feature in
the kernel configuration file (GENERIC, or any other in the directory).
