The original intent of this file was to list limitations in drivers/hardware relating to multicast use, back when some modest hardware from the early 1990s did not support things we might take for granted today. I was intending to delete some now-gone MCA/token ring entries in this file, but once I opened it, I found it only contained information on the earliest (pre-2000) linux networking drivers. Checking the git history shows that the file hasn't been touched since 2005. Clearly nobody is actively consulting this file as a meaningful reference. Rather than add a "YES YES YES" line for all of the drivers we currently have, lets just take advantage of the fact that nobody is using the file to delete it. This has the side benefit of not having to do a line-by-line deletion of the file content as each older driver is expired. Signed-off-by:

Commit 46d3ceab "tcp: TCP Small Queues" has severly degraded performance for single connection RR workloads on HiperSockets with MTU >=16K due to a conflict of the TCP Small Queues approach with our buffer scan threshold which releases buffers not frequently enough yet. This fix restores performance to the same level as before cited commit. Signed-off-by:

As of now, s390dbf entries for the cards are discarded as soon as the device is removed. However, this will also bar us of all chances of getting valuable debug information after a device has been removed. This patch will keep the s390dbf entries around until the qeth module is removed.

The existing port isolation mode 'forward' will now verify that the adjacent switch port supports the required reflective relay (RR) mode. This patch adds the required error handling for the cases where enabling port isolation mode 'forward' can now fail. Furthermore, once established, we never fall back from one of the port isolation modes to a non-isolated mode without further user-interaction. This includes cases where the isolation mode was enabled successfully, but ceases to work e.g. due to configuration changes at the switch port. Finally, configuring an isolation mode with the device being offline will make onlining the device fail permanently upon errors encountered until either errors are resolved or the isolation mode is changed by the user to a different mode.

YOSHIFUJI Hideaki says: ==================== This series of changes basically clean up NDISC logic, especially on sender side. We originally do For NS/NA/RS: 1) build temporary ICMPv6 header 2) ndisc_build_skb() with temporary ICMPv6 header and rather criptic arguments. - Calculate total length and allocate sk_buff - Build IPv6 header. - copy ICMPv6 header, additional data and ND options. - Fill-in ICMPv6 checksum. Here, structures defined for message format was not used at all, it is difficult to understand what is being sent, and it was not generic. 3) __ndisc_send() - Allocate temporary dst. - Send it. Several issues: - We could not defer decision if we should/can send some ND option. - It is hard to see the packet format at a glance. - ICMPv6 header was built as temporary variable, and then copied to the buffer. - Some code path for Redirect was not shared. With these patches, we do: 1) Calculate (or estimate) message length and option length. 2) Allocate skb (via new ndisc_skb_alloc()). 3) Fill-in ICMPv6 message directly using compound literals. 4) Fill-in ICMPv6 checksum 5) Build IPv6 header (including length) 6) Send the packet (via ndisc_send_skb()). - allocate temporary dst and send it. - We can defer calculating real length of the packet. For example, we can give up filling some option at when filling in. - Message is built directly without temporary buffer. - Structures defined for message format is easier to understand what is being built. - NS/NA/RS/Redirect share same logic. - Reduced code/data size: text data bss dec hex filename 265407 14133 3488 283028 45194 old/net/ipv6/ipv6.o 264955 14109 3488 282552 44fb8 new/net/ipv6/ipv6.o ==================== Signed-off-by: -
