Re: [PATCH 1/3] net:phy:dp83867: fix speed 10 in sgmii mode

omething is wrong with mdio bus. I.e. write returned error. And it's more likely hardware bug which needs to be fixed. Once I used to not print this error on each ifconfig up/down.

Re: [PATCH v1 RFC 1/1] Add Microchip KSZ8795 DSA driver

Hello Tristram, in previous version I see that transit traffic (ping) goes to cpu, then from cpu back to destination port. I.e. it works but with cpu involving. Is this version supposed to work like that? Thank you, Maxim. 2017-10-06 23:33 GMT+03:00 : > From: Tristram Ha > > Add Microchip KSZ8

Re: [PATCH] DSA support for Micrel KSZ8895

are library. Both driver and DSA driver. Driver has to work with some minor fixups related to your kernel version. But I think they are don't care about up-streaming that code. So you can take their code as a reference. -- Best regards, Maxim Uvarov
