2020-05-01net: atlantic: A2 ingress / egress hw configurationIgor Russkikh
Chip generations are mostly compatible register-wise, but there are still some differences. Therefore we've made some of first generation (A1) code non-static to re-use it where possible. Some pieces are A2 specific, in which case we redefine/extend such APIs.

2020-05-01r8169: simplify counter handlingHeiner Kallweit

2020-05-01r8169: remove redundant driver message when entering promiscuous modeHeiner Kallweit
Net core - __dev_set_promiscuity - prints a message already when promiscuous mode in entered/left, therefore we don't have to do this in the driver too. Also the driver message would be misleading (would be because "link" message level is disabled per default) because it would print "promisc mode enabled" even if it's being left. Reason is that __dev_change_flags() calls dev_set_rx_mode() before touching the promisc flag. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S.

2020-04-30net: usb: ax88179_178a: Implement ethtool_ops set_eepromBjorn Andersson
The vendor driver does upon failing to read a valid MAC address from EEPROM write the netdev's address back to EEPROM and invoking a EEPROM reload operation. Based on this we can implement the ethtool_ops set_eeprom and provide the means to populate the EEPROM from within Linux. It's worth noting that ax88179_get_eeprom() will return some default data unless the content of the EEPROM is deemed "complete", so until the EEPROM is fully populated (e.g. by running ethtool -e | ethtool -E) data written with ax88179_set_eeprom() will appear not to stick. The implementation is based on asix_set_eeprom(), from asix_common.c Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
