2018-04-19net-next: ax88796: Attach MII bus only when openMichael Karcher1-88/+95
Call ax_mii_init in ax_open(), and unregister/remove mdiobus resources in ax_close(). This is needed to be able to unload the module, as the module is busy while the MII bus is attached.

The Asix Electronics PHY found on the X-Surf 100 Amiga Zorro network card by Individual Computers is buggy, and needs the reset bit toggled as workaround to make a PHY soft reset succeed.

2018-04-19hv_netvsc: propogate Hyper-V friendly name into interface aliasStephen Hemminger1-0/+28
This patch implement the 'Device Naming' feature of the Hyper-V network device API. In Hyper-V on the host through the GUI or PowerShell it is possible to enable the device naming feature which causes the host to make available to the guest the name of the device. This shows up in the RNDIS protocol as the friendly name. The name has no particular meaning and is limited to 256 characters. The value can only be set via PowerShell on the host, but could be scripted for mass deployments. The default value is the string 'Network Adapter' and since that is the same for all devices and useless, the driver ignores it. In Windows, the value goes into a registry key for use in SNMP ifAlias. For Linux, this patch puts the value in the network device alias property; where it is visible in ip tools and SNMP. The host provided ifAlias is just a suggestion, and can be overridden by later ip commands. Also requires exporting dev_set_alias in netdev core.

2018-04-19r8169: remove jumbo_tx_csum from chip config structHeiner Kallweit1-79/+54
According to the chip configuration entries only RTL8169 (ver <= 06) supports tx checksumming for jumbo packets. By the way: constant JUMBO_1K is a little misleading because it refers to the standard packet size and not to a jumbo packet size. By implementing this rule we can get rid of configuring tx checksumming support per chip type. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S.

2018-04-19r8169: replace rx_buf_sz with a constantHeiner Kallweit1-19/+18
rx_buf_sz is constant, so we don't have to pass it as parameter and in general can replace it with a constant. When working on this I noticed that also before in rtl_set_rx_max_size() a value of 0x4000 is set, what is not in line with the chip spec. According to the spec only bits 0..13 are used and we set an effective value of zero therefore. However, the driver still seems to work and due to potential side effects I'm reluctant to make a change. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S.
