* net: asix: autoneg will set WRITE_MEDIUM regRobert Foss2016-09-011-4/+1
| | | | | | | | | | | | | | | | | | From: Grant Grundler <[email protected]> The miii_nway_restart() causes a PHY link change activity and ax88772_link_reset will be called. link_reset will set AX_CMD_WRITE_MEDIUM_MODE register correctly. The asix_write_medium_mode in reset() fills in a default value to the register which may be different from the negotiation result. So do this first. Ignore the ret value since it's ignored in XXX_link_reset() functions.

IEEE 802.3 spec section "22.2.4.1.1 Reset" requires up to 500ms delay. Mitigate the "max" delay by polling the phy until BCM_RESET bit is clear.

* asix: Do full reset during ax88772_bindCharles Keepax2014-11-071-13/+1
| | | | | | | | | | | | | | | | | | | | | | commit 3cc81d85ee01 ("asix: Don't reset PHY on if_up for ASIX 88772") causes the ethernet on Arndale to no longer function. This appears to be because the Arndale ethernet requires a full reset before it will function correctly, however simply reverting the above patch causes problems with ethtool settings getting reset. It seems the problem is that the ethernet is not properly reset during bind, and indeed the code in ax88772_bind that resets the device is a very small subset of the actual ax88772_reset function. This patch uses ax88772_reset in place of the existing reset code in ax88772_bind which removes some code duplication and fixes the ethernet on Arndale. It is still possible that the original patch causes some issues with suspend and resume but that seems like a separate issue and I haven't had a chance to test that yet.

* asix: Don't reset PHY on if_up for ASIX 88772Michel Stam2014-10-031-1/+1
| | | | | | | | | | | | | | | | I've noticed every time the interface is set to 'up,', the kernel reports that the link speed is set to 100 Mbps/Full Duplex, even when ethtool is used to set autonegotiation to 'off', half duplex, 10 Mbps. It can be tested by: ifconfig eth0 down ethtool -s eth0 autoneg off speed 10 duplex half ifconfig eth0 up Then checking 'dmesg' for the link speed.

* net: asix: add missing flag to struct driver_infoEmil Goode2014-02-141-1/+2
| | | | | | | | | | | | | The struct driver_info ax88178_info is assigned the function asix_rx_fixup_common as it's rx_fixup callback. This means that FLAG_MULTI_PACKET must be set as this function is cloning the data and calling usbnet_skb_return. Not setting this flag leads to usbnet_skb_return beeing called a second time from within the rx_process function in the usbnet module.

* USBNET: centralize computing of max rx/tx qlenMing Lei2013-07-281-0/+3
| | | | | | | | | | | | | | | | | | | | This patch centralizes computing of max rx/tx qlen, because: - RX_QLEN()/TX_QLEN() is called in hot path - computing depends on device's usb speed, now we have ls/fs, hs, ss, so more checks need to be involved - in fact, max rx/tx qlen should not only depend on device USB speed, but also depend on ethernet link speed, so we need to consider that in future. - if SG support is done, max tx qlen may need change too Generally, hard_mtu and rx_urb_size are changed in bind(), reset() and link_reset() callback, and change mtu network operation, this patches introduces the API of usbnet_update_max_qlen(), and calls it in above path.

* usb/net/asix_devices: Add USBNET HG20F9 ethernet dongleGlen Turner2013-02-271-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | This USB ethernet adapter was purchased in anodyne packaging from the computer store adjacent to linux.conf.au 2013 in Canberra (Australia). A web search shows other recent purchasers in Lancaster (UK) and Seattle (USA). Just like an emergent virus, our age of e-commerce and airmail allows underdocumented hardware to spread around the world instantly using the vector of ridiculously low prices. Paige Thompson, infected via eBay, discovered that the HG20F9 is a copy of the Asix 88772B; many viruses copy the RNA of other viruses. See Paige's work at <https://github.com/paigeadele/HG20F9>. This patch uses her discovery to update the restructured Asix driver in the current kernel. Just as some viruses inhabit seemingly-healthy cells, the HG20F9 uses the Vendor ID 0x066b assigned to Linksys Inc. For the present there is no clash of Product ID 0x20f9.

|/ | | | | | | | | | | | | | The dbg() USB macro is so old, it predates me. The USB networking drivers are the last hold-out using this macro, and we want to get rid of it, so replace the usage of it with the proper netdev_dbg() or dev_dbg() (depending on the context) calls. Some places we end up using a local variable for the debug call, so also convert the other existing dev_* calls to use it as well, to save tiny amounts of code space.

It cannot handle odd length values (accesses must be aligned at 16 bit boundaries) and interprets the offset provided by ethtool as 16 bit word offset instead as byte offset. The new code for asix_get_eeprom() introduced by this patch is modeled after the code in drivers/net/ethernet/atheros/atl1e/atl1e_ethtool.c and provides read access to the entire EEPROM with arbitrary offsets and lengths.
