By adding batadv_send_skb_to_orig() in send.c, we can remove duplicate code that looks up the next hop and then calls batadv_send_skb_packet(). Furthermore, this prepares the upcoming new implementation of fragmentation, which requires the next hop to route packets. Please note that this doesn't entirely remove the next-hop lookup in routing.c and unicast.c, since it is used by the current fragmentation code. Also note that the next-hop info is removed from debug messages in translation-table.c, since it is looked up elsewhere. Signed-off-by:

This patch adds support for an array of debugfs general (not soft_iface specific) attributes. With this change it will be possible to add more general attributes by simply appending them to the array without touching the rest of the code. Reported-by:

The transtable_global debug file can show multiple entries for a single client when multiple gateways exist. The chosen gateway isn't marked in the list and therefore the user cannot easily debug the situation when there is a problem with the currently used gateway. The best gateway is now marked with "*" and secondary gateways are marked with "+". Signed-off-by:

In the event that an association exceeds its max_retrans attempts, we should send an ABORT chunk indicating that we are closing the assocation as a result. Because of the nature of the error, its unlikely to be received, but its a nice clean way to close the association if it does make it through, and it will give anyone watching via tcpdump a clue as to what happened. Change notes: v2) * Removed erroneous changes from sctp_make_violation_parmlen Signed-off-by:

This patch provides extensions to VXLAN for supporting Distributed Overlay Virtual Ethernet (DOVE) networks. The patch includes: + a dove flag per VXLAN device to enable DOVE extensions + ARP reduction, whereby a bridge-connected VXLAN tunnel endpoint answers ARP requests from the local bridge on behalf of remote DOVE clients + route short-circuiting (aka L3 switching). Known destination IP addresses use the corresponding destination MAC address for switching rather than going to a (possibly remote) router first. + netlink notification messages for forwarding table and L3 switching misses Changes since v2 - combined bools into "u32 flags" - replaced loop with !is_zero_ether_addr() Signed-off-by:

If ndo_validate_addr is set to the generic eth_validate_addr function there is no point in calling is_valid_ether_addr from driver ndo_open if ndo_open is not used elsewhere in the driver. With this change is_valid_ether_addr will be called from the generic eth_validate_addr function. So there should be no change in the actual behavior. Signed-off-by:

Move to circular buffers management macro and correct an error with circular buffer initial condition. Without this patch, the macb_tx_ring_avail() function was not reporting the proper ring availability at startup: macb macb: eth0: BUG! Tx Ring full when queue awake! macb macb: eth0: tx_head = 0, tx_tail = 0 And hanginig forever... I remove the macb_tx_ring_avail() function and use the proven macros from circ_buf.h. CIRC_CNT() is used in the "consumer" part of the driver: macb_tx_interrupt() to match advice from Documentation/circular-buffers.txt. Reported-by:
