Switch bindings for spi managed mode are using spaces instead of tabs.
Fix them to get a file with a proper kernel indentation style.

I don't know if at the end this is going to be changed together with
spi etc to use regmap API but I tested this code as it is and it
works. So you can add my Tested-by if you want:

I think is useful. If not at least add a clarification that the reg
"5f" for the i2c is the one to use.

Hi,
This is because if you change the skb you must calcutale checksum for
tcp and ip headers changes again. For example:
struct iphdr *new_iph = NULL;
struct tcphdr *new_th = NULL;
/* copy skb to another skb with skb_copy */
new_skb = skb_copy_expand(skb, skb_headroom(skb), MY_SIZE, GFP_ATOMIC);
27 matches
