net: fix harmonize_features() vs NETIF_F_HIGHDMA
commit 7be2c82cfd5d28d7adb66821a992604eb6dd112e upstream.
Ashizuka reported a highmem oddity and sent a patch for freescale
fec driver.
But the problem root cause is that core networking stack
must ensure no skb with highmem fragment is ever sent through
a device that does not assert NETIF_F_HIGHDMA in its features.
We need to call illegal_highdma() from harmonize_features()
regardless of CSUM checks.
Fixes: ec5f06156423 ("net: Kill link between CSUM and SG features.")
