ipv4: use separate genid for next hop exceptions
commit
13d82bf5 (ipv4: Fix flushing of cached routing informations)
added the support to flush learned pmtu information.
However, using rt_genid is quite heavy as it is bumped on route
add/change and multicast events amongst other places. These can
happen quite often, especially if using dynamic routing protocols.
While this is ok with routes (as they are just recreated locally),
the pmtu information is learned from remote systems and the icmp
notification can come with long delays. It is worthy to have separate
genid to avoid excessive pmtu resets.

Forcing uninitialized state allows us to upgrade and reinitialize the adapter.
FW_VERSION_T4 = 1.4.0.0
FW_VERSION_T5 = 0.0.0.0
At this point driver supports above and greater than above version of firmware.
If it doesn't find the required firmware version than it forces the adapter to
be reinitialized as shown below.
1) If FW_ON_ADAPTER < FW_VERSION and we're the MASTER_PF force uninitialized
state and a FW upgrade if available.
- If FW_ON_ADAPTER < /lib/firmware/cxgb4/t*fw.bin we will update the
adapters FW.
- If FW_ON_ADAPTER >= /lib/firmware/cxgb4/t*fw.bin don't upgrade FW.
- If upgrade_fw() fails force reinitialization of the adapter anyways,

tcp: fix undo on partial ack in recovery
Upon detecting spurious fast retransmit via timestamps during recovery,
use PRR to clock out new data packet instead of retransmission. Once
all retransmission are proven spurious, the sender then reverts the
cwnd reduction and congestion state to open or disorder.
The current code does the opposite: it undoes cwnd as soon as any
retransmission is spurious and continues to retransmit until all
data are acked. This nullifies the point to undo the cwnd because
the sender is still retransmistting spuriously. This patch fixes
it. The undo_ssthresh argument of tcp_undo_cwnd_reductiuon() is no
longer needed and is removed.

tcp: consolidate PRR packet accounting
This patch series fixes an undo bug in fast recovery: the sender
mistakenly undos the cwnd too early but continues fast retransmits
until all pending data are acked. This also multiplies the SNMP
stat PARTIALUNDO events by the degree of the network reordering.
The first patch prepares the fix by consolidating the accounting
of newly_acked_sacked in tcp_cwnd_reduction(), instead of updating
newly_acked_sacked everytime sacked_out is adjusted. Also pass
acked and prior_unsacked as const type because they are readonly

Ethernet controllers found on Kirkwood SoCs not only suffer from loosing

affected as it installs a clock gating workaround because of the MAC

batman-adv: move batadv_slide_own_bcast_window to bat_iv_ogm.c
batadv_slide_own_bcast_window() is used only in bat_iv_ogm.c
and it is currently touching only batman_iv specific
attributes.
Move it into bat_iv_ogm.c and make it static.

batman-adv: move ring_buffer helper functions in bat_iv_ogm
the two lonely ring_buffer helper functions are used by the
bat_iv_ogm module only and therefore they can be moved
inside it.

batman-adv: use eth_hdr() when it makes sense
Instead of casting the result of skb_mac_header() to
"struct ethhdr *" every time, the eth_hdr inline function
can be use to beautify the code and improve its readability.

batman-adv: do not silently ignore wrong condition
Only one neigh_node per orig_node should match a given
neighbor address, therefore, if more than one matching
neigh_node is found, a WARNING has to be triggered to let
the user know that something is wrong in the originator
state instead of silently skipping the error.

batman-adv: don't check compat version twice
Compatibility version is checked upon packet reception
