This breaks the networking on Zynq. - -The commit message adding this states: a new capability so that -macb_set_tx_clock() to not be called for IPs having this -capability - -This strongly implies that present of the flag was intended to skip -the function not absence of the flag. Update the if statement to -this effect, which repairs the existing users. - -Fixes: daafa1d33cc9 ("net: macb: add capability to not set the clock rate") -Suggested-by: Andrew Lunn <andrew@lunn.ch> -Signed-off-by: Charles Keepax <ckeepax@opensource.cirrus.com> -Reviewed-by: Claudiu Beznea <claudiu.beznea@microchip.com> -Reviewed-by: Andrew Lunn <andrew@lunn.ch> -Link: https://lore.kernel.org/r/20210104103802.13091-1-ckeepax@opensource.cirrus.com -Signed-off-by: Jakub Kicinski <kuba@kernel.org> ---- - drivers/net/ethernet/cadence/macb_main.c | 2 +- - 1 file changed, 1 insertion(+), 1 deletion(-) - ---- a/drivers/net/ethernet/cadence/macb_main.c -+++ b/drivers/net/ethernet/cadence/macb_main.c -@@ -464,7 +464,7 @@ static void macb_set_tx_clk(struct macb - { - long ferr, rate, rate_rounded; - -- if (!bp->tx_clk || !(bp->caps & MACB_CAPS_CLK_HW_CHG)) -+ if (!bp->tx_clk || (bp->caps & MACB_CAPS_CLK_HW_CHG)) - return; - - switch (speed) { |
