Add support for conditionally setting the ip_alignement flag AX_RX_CTL_IPE in AX_RX_CTL and make sure that AX_RX_CTL_DROPCRCERR is also set to be consistent with the initial configuration in ax88179_reset() Signed-off-by: Birger Koblitz <redacted> Reviewed-by: Andrew Lunn <andrew@lunn.ch> --- drivers/net/usb/ax88179_lib.c | 8 ++++++-- drivers/net/usb/ax88179a_devices.c | 1 + 2 files changed, 7 insertions(+), 2 deletions(-)
