Conflicts: drivers/net/ethernet/broadcom/bnx2x/bnx2x_cmn.c The bnx2x gso_type setting bug fix in 'net' conflicted with changes in 'net-next' that broke the gso_* setting logic out into a seperate function, which also fixes the bug in question. Thus, use the 'net-next' version. Signed-off-by: David S. Miller <davem@davemloft.net>

Until now, the MPC5200 FEC ethernet driver relied upon the bootloader (U-Boot) to write the MAC address into the ethernet controller registers. The Linux driver should not rely on such a thing. So lets read the MAC address from the DT as it should be done here. The following priority is now used to read the MAC address: 1) First, try OF node MAC address, if not present or invalid, then: 2) Read from MAC address registers, if invalid, then: 3) Log a warning message, and choose a random MAC address. This fixes a problem with a MPC5200 board that uses the SPL U-Boot version without FEC initialization before Linux booting for boot speedup. Additionally a status line is now be printed upon successful driver probing, also displaying this MAC address.

The CPSW switch can act as Dual EMAC by segregating the switch ports using VLAN and port VLAN as per the TRM description in 14.3.2.10.2 Dual Mac Mode Following CPSW components will be common for both the interfaces. * Interrupt source is common for both eth interfaces * Interrupt pacing is common for both interfaces * Hardware statistics is common for all the ports * CPDMA is common for both eth interface * CPTS is common for both the interface and it should not be enabled on both the interface as timestamping information doesn't contain port information. Constrains * Reserved VID of One port should not be used in other interface which will enable switching functionality * Same VID must not be used in both the interface which will enable switching functionality Signed-off-by: Mugunthan V N <mugunthanvnm@ti.com> Signed-off-by: David S.

John W. Linville says: ==================== Here is another handful of late-breaking fixes intended for the 3.8 stream... Hopefully the will still make it! :-) There are three mac80211 fixes pulled from Johannes: "Here are three fixes still for the 3.8 stream, the fix from Cong Ding for the bad sizeof (Stephen Hemminger had pointed it out before but I'd promptly forgotten), a mac80211 managed-mode channel context usage fix where a downgrade would never stop until reaching non-HT and a bug in the channel determination that could cause invalid channels like HT40+ on channel 11 to be used." Also included is a mwl8k fix that avoids an oops when using mwl8k devices that only support the 5 GHz band. Please let me know if there are problems! ==================== Signed-off-by: David S.

The original fix that was applied for setting gso_type required more change than necessary because it was assumed ixgbe does RSC on IPv6 frames and this is not correct. RSC is only supported with IPv4/TCP frames only. As such we can simplify the fix and avoid the unnecessary move of eth_type_trans. The previous patch "ixgbe: fix gso type" and this patch reduce the entire fix to one line that sets gso_type to TCPV4 if the frame is RSC.

__netpoll_rcu_free is used to free netpoll structures when the rtnl_lock is already held. The mechanism is used to asynchronously call __netpoll_cleanup outside of the holding of the rtnl_lock, so as to avoid deadlock. Unfortunately, __netpoll_cleanup modifies pointers (dev->np), which means the rtnl_lock must be held while calling it. Further, it cannot be held, because rcu callbacks may be issued in softirq contexts, which cannot sleep. Fix this by converting the rcu callback to a work queue that is guaranteed to get scheduled in process context, so that we can hold the rtnl properly while calling __netpoll_cleanup Tested successfully by myself.

The band field for the supported channels were left unpopulated, making them default to 0 == IEEE80211_BAND_2GHZ, even for the 5GHz channels. This resulted in null pointer accesses if anything tries to access wiphy->bands[channel->band] of a 5GHz channel on 5GHz only cards, since wiphy->bands[2GHZ] is NULL for them (e.g. cfg80211_chandef_usable does).

When trying to connect to an AP that advertises HT but not VHT, the mac80211 code erroneously uses the configuration from the AP as is instead of checking it against regulatory and local capabilities. This can lead to using an invalid or even inexistent channel (like 11/HT40+). Additionally, the return flags from downgrading must be ORed together, to collect them from all of the downgrades. Also clarify the message. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

YOSHIFUJI Hideaki / 吉藤英明 authored
To allow both of protocol-specific data and device-specific data attached with neighbour entry, and to eliminate size calculation cost when allocating entry, sizeof protocol-speicic data must be multiple of NEIGH_PRIV_ALIGN. On 64bit archs, sizeof(struct dn_neigh) is multiple of NEIGH_PRIV_ALIGN, but on 32bit archs, it was not. Introduce NEIGH_ENTRY_SPACE() macro to ensure that protocol-specific entry-size meets our requirement.

Pablo Neira Ayuso says: ==================== The following patchset contains Netfilter/IPVS fixes for 3.8-rc7, they are: * Fix oops in IPVS state-sync due to releasing a random memory area due to unitialized pointer, from Dan Carpenter. * Fix SCTP flow establishment due to bad checksumming mangling in IPVS, from Daniel Borkmann. * Three fixes for the recently added IPv6 NPT, all from YOSHIFUJI Hideaki, with an amendment collapsed into those patches from Ulrich Weber. They fiix adjustment calculation, fix prefix mangling and ensure LSB of prefixes are zeroes (as required by RFC). Specifically, it took me a while to validate the 1's complement arithmetics/ checksumming approach in the IPv6 NPT code. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
