Fix e1000e_rar_set() to flush consecutive register writes to avoid write combining which some parts cannot handle. Update e1000e_init_rx_addrs() to call the fixed e1000e_rar_set() instead of duplicating code. Also change e1000e_rar_set() to _not_ set the Address Valid bit if the MAC address is all zeros.

In the driver probe function the emac module clock needs to be enabled before calling register_netdev().

The Davicom DM9100 and DM9102 chips are used on the motherboards of some SPARC systems (supported by the tulip driver) and also in PCI expansion cards (supported by the dmfe driver). There is no difference in the PCI device ids for the two different configurations, so these drivers both claim the device ids. However, it is possible to distinguish the two configurations by the presence of Open Firmware properties for them, so we do that.

If NET_SKB_PAD is not a multiple of the cache line size, mv643xx_eth allocates a couple of extra bytes at the start of each receive buffer to make the data payload end up on a cache line boundary. These extra bytes are skb_reserve()'d before DMA mapping, so they should not be included in the DMA map byte count (as the mapping is done starting at skb->data), nor should they be included in the receive descriptor buffer size field, or the hardware can end up DMAing beyond the end of the buffer, which can happen if someone sends us a larger-than-MTU sized packet. This problem was introduced in commit 7fd96ce4 ("mv643xx_eth: rework receive skb cache alignment", May 6 2009), but hasn't appeared to be problematic so far, probably as the main users of mv643xx_eth all have NET_SKB_PAD == L1_CACHE_BYTES.

When we have L3 tunnels with different inner/outer families (i.e. IPV4/IPV6) which use a multicast address as the outer tunnel destination address, multicast packets will be loopbacked back to the sending socket even if IP*_MULTICAST_LOOP is set to disabled. The mc_loop flag is present in the family specific part of the socket (e.g. the IPv4 or IPv4 specific part). setsockopt sets the inner family mc_loop flag. When the packet is pushed through the L3 tunnel it will eventually be processed by the outer family which if different will check the flag in a different part of the socket then it was set.

The ipvs code has a nifty system for doing the size of ioctl command copies; it defines an array with values into which it indexes the cmd to find the right length. Unfortunately, the ipvs code forgot to check if the cmd was in the range that the array provides, allowing for an index outside of the array, which then gives a "garbage" result into the length, which then gets used for copying into a stack buffer. Fix this by adding sanity checks on these as well as the copy size.
