[patch 2/2] s390: some qeth driver fixes

From: Frank Pavlic <fpavlic@de.ibm.com>
	- fixed kernel panic when using EDDP support in Layer 2 mode
	- NULL pointer exception in qeth_set_offline fixed.
	- setting EDDP in Layer 2 mode did not set NETIF_F_(SG/TSO)
	  flags when device became online.
	- use sscanf for parsing and converting IPv4 addresses
	  from string to __u8 values.
	- qeth_string_to_ipaddr6 fixed. in case of double colon
	  the converted IPv6 address out from the string was not correct
	  in previous implementation.
