Final nlmsg_len field update must reflect inserted net_dm_drop_point
data.

This patch depends on previous patch:
"drop_monitor: add missing call to genlmsg_end"

Signed-off-by: Reiter Wolfgang <redacted>

Several coding style errors:

There must be a space between "if" and "(skb)"

+		struct nlmsghdr *nlh = (struct nlmsghdr *)skb->data;
+		struct genlmsghdr *gnlh = (struct genlmsghdr *)nlmsg_data(nlh);
+		genlmsg_end(skb, genlmsg_data(gnlh));
+	}

There should be an empty line between the local variable declarations
and actual code.
