batman-adv: remove FSF address from GPL disclaimer As suggested by checkpatch, remove all the references to the FSF address since the kernel already has one reference in its documentation.

batman-adv: send GW_DEL event when the gw client mode is deselected Whenever the GW client mode is deselected, a DEL event has to be sent in order to tell userspace that the current gateway has been lost. Send the uevent on state change only if a gateway was currently selected.

batman-adv: rename gw_deselect() to gw_reselect() The function batadv_gw_deselect() is actually not deselecting anything. It is just informing the GW code to perform a re-election procedure when possible. The current gateway is not being touched at all and therefore the name of this function is rather misleading. Rename it to batadv_gw_reselect() to batadv_gw_reselect() to make its behaviour easier to grasp.

batman-adv: tvlv - gateway download/upload bandwidth container Prior to this patch batman-adv read the advertised uplink bandwidth from userspace and compressed this information into a single byte called "gateway class". Now the download & upload bandwidth information is sent as-is. No userspace change is necessary since the sysfs API always allowed to specify a bandwidth.

batman-adv: Prefix gateway-client non-static functions with batadv_ batman-adv can be compiled as part of the kernel instead of an module. In that case the linker will see all non-static symbols of batman-adv and all other non-static symbols of the kernel. This could lead to symbol collisions. A prefix for the batman-adv symbols that defines their private namespace avoids such a problem. Reported-by: David Miller <davem@davemloft.net> Signed-off-by: Sven Eckelmann <sven@narfation.org>

batman-adv: fix potential kernel paging errors for unicast transmissions There are several functions which might reallocate skb data. Currently some places keep reusing their old ethhdr pointer regardless of whether they became invalid after such a reallocation or not. This potentially leads to kernel paging errors. This patch fixes these by refetching the ethdr pointer after the potential reallocations.

batman-adv: send every DHCP packet as bat-unicast In different situations it is possible that the DHCP server or client uses broadcast Ethernet frames to send messages to each other. The GW component in batman-adv takes care of using bat-unicast packets to bring broadcast DHCP Discover/Requests to the "best" server. On the way back the DHCP server usually sends unicasts, but upon client request it may decide to use broadcasts as well. This patch improves the GW component so that it now snoops and sends as unicast all the DHCP packets, no matter if they were generated by a DHCP server or client.
