2017-06-10net: aquantia: atlantic: remove declaration of hw_atl_utils_hw_set_powerPhilippe Reynes
This function is not defined, so no need to declare it. As I don't have the hardware, I'd be very pleased if someone may test this patch. Signed-off-by: Philippe Reynes <tremyfr@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-05-11ethernet: aquantia: remove redundant checks on error statusColin Ian King
The error status err is initialized as zero and then being checked several times to see if it is less than zero even when it has not been updated. It may seem that the err should be assigned to the return code of the call to the various *offload_en_set calls and then we check for failure, however, these functions are void and never actually return any status. Since these error checks are redundant we can remove these as well as err and the error exit label err_exit.

2017-05-08aquantia: Fix "ethtool -S" crash when adapter down.Pavel Belous
This patch fixes the crash that happens when driver tries to collect statistics from already released "aq_vec" object. If adapter is in "down" state we still allow user to see statistics from HW.

When the aquantia device mtu is changed the net_device structure is not updated. As a result the ip command does not properly reflect the mtu change. Commit 5513e16421cb incorrectly assumed that __dev_set_mtu() was making the assignment ndev->mtu = new_mtu; This is not true in the case where the driver has a ndo_change_mtu routine.
