There exist different commands to add unicast and multicast addresses on the OSA card. rxip addresses are always set as unicast addresses and thus just unicast addresses should be allowed. Adding a multicast address now fails and a grace message is generated. Signed-off-by:

Replace some open-coded parts with their proper API calls. Also remove two skb_[re]set_mac_header() calls in the L2 xmit paths that are clearly no longer required, since at least commit 6d1ccff6 ("net: reset mac header in dev_start_xmit()"). Signed-off-by:

For some xmit paths we pass down a data offset to qeth_fill_buffer(), to indicate that the first k bytes of the skb should be skipped when mapping it into buffer elements. Commit acd9776b ("s390/qeth: no ETH header for outbound AF_IUCV") recently switched the offset for the IUCV-over-HiperSockets path from 0 to ETH_HLEN, and now we have device offset OSA = 0 IQD > 0 for all xmit paths. OSA would previously pass down -1 from do_send_packet(), to distinguish between 1) OSA and 2) IQD with offset 0. That's no longer needed now, so have it pass 0, make the offset unsigned and clean up how we apply the offset in __qeth_fill_buffer(). No change of behaviour for any of our current xmit paths.

qeth_l3_setadapter_parms() queries the device for supported adapterparms, even though they already have been queried as part of the device's high-level setup. Remove that extra call. The only call chain for qeth_l3_setadapter_parms() is __qeth_l3_set_online() qeth_core_hardsetup_card() qeth_query_setadapterparms() qeth_l3_setadapter_parms() qeth_query_setadapterparms() , and we only reach qeth_l3_setadapter_parms() if the first adapterparms query succeeds. Hence removing the second query results in no loss of functionality. Signed-off-by:

After transmitting a skb via send_packet[_fast](), the statistics code accesses the skb once more to account for transmitted page frags. This has a (theoretical?) race against the TX completion - if the TX completion is processed and frees the skb before hard_start_xmit() gets to the statistics part, we access random memory. Fix this by caching the # of page frags, before the skb is transmitted. Signed-off-by:

The fw_type module parameter isn't showing up in the /sys/module/liquidio/parameters directory. Fix it by setting the read permission bits for user, group, other in module_param_string(). Revise the description of fw_type. Initialize the fw_type static char array with the default value to conform to the module parameter description. Signed-off-by:

Jiri Pirko says: ==================== mlxsw: Add support for nexthop group consolidation for IPv6 Arkadi says: Due to limited ASIC resources the maximum number of routes is limited by the nexthop resource. In order to improve the routing scale nexthop consolidation should be performed. In case of IPv4, the kernel does the consolidation of nexthops in the form of the fib_info struct. In that case, the driver uses the fib_info's address as a key for the internal nexthop group representative struct lookup. In case of IPv6, the kernel doesn't do consolidation, thus the driver should implement it by itself. The hash value is calculated based on the nexthop set, by performing bitwise xor on the ifindexs of the nexthops, in a similar way to IPV4's kernel implementation. In case of collision a full match is performed between the sets which include address and ifindex comparison. In order to use the same hash table in both cases (IPv4/6), the rhashtable is changed to operate on variable length key. ==================== Signed-off-by: -

Due to limited ASIC resources the maximum number of routes is limited by the nexthop resource. In order to improve the routing scale nexthop consolidation should be performed. This patch adds support for IPv6 neighbor consolidation. The hash value is calculated based on the nexthop set, by performing bitwise xor on the ifindexs of the nexthops, in a similar way to IPv4's kernel implementation. In case of collision a full match is performed between the sets which include address and ifindex comparison. Non gateway nexthop groups are not inserted to the hash table due to lack of nexthop device (ifindex). Signed-off-by:

This patch does preparation before introducing IPv6 nexthop group consolidation. Currently the nexthop group hash table is used only by IPv4 and uses fixed key size. In order to support the IPv6's variable length key the current table is changed. Signed-off-by:

Jiri Pirko says: ==================== mlxsw: spectrum_router: Increase VRF scale Ido says: The purpose of this set is to increase the maximum number of supported VRF devices on top of the Spectrum ASIC under different workloads. This is achieved by sharing the same LPM tree across all the virtual routers for a given L3 protocol (IPv4 / IPv6). The change is explained in detail in the third patch. First two patches are small changes to make review easier. ==================== Signed-off-by: -
Ido Schimmel authored
The number of LPM trees available for lookup is much smaller than the number of virtual routers, which are used to implement VRFs. In addition, an LPM tree can only be used by one protocol - either IPv4 or IPv6. Therefore, in order to increase the number of supported virtual routers to the maximum we need to be able to share LPM trees across virtual routers instead of trying to find an optimized tree for each. Do that by allocating one LPM tree for each protocol, but make sure it will only include prefixes that are actually used, so as to not perform unnecessary lookups. Since changing the structure of a bound tree isn't recommended, whenever a new tree it required, it's first created and then bound to each virtual router, replacing the old one. Signed-off-by:

Ido Schimmel authored
Instead of relying on the LPM tree to be assigned to the virtual router before binding the two, lets pass it explicitly. This will later allow us to return upon binding error instead of having to perform a rollback of the assignment. Signed-off-by:

There is no point in returning a value from function whose return value is never checked. Even if the return value was checked, there wouldn't be anything to do about it, as these functions are either called from error or deletion paths. Signed-off-by:
