Vlad Zolotarov authored
New FW/HSI (7.0): - Added support to 578xx chips - Improved HSI - much less driver's direct access to the FW internal memory needed. New implementation of the HSI handling layer in the bnx2x (bnx2x_sp.c): - Introduced chip dependent objects that have chip independent interfaces for configuration of MACs, multicast addresses, Rx mode, indirection table, fast path queues and function initialization/cleanup. - Objects functionality is based on the private function pointers, which allows not only a per-chip but also PF/VF differentiation while still preserving the same interface towards the driver. - Objects interface is not influenced by the HSI changes which do not require providing new parameters keeping the code outside the bnx2x_sp.c invariant with regard to such HSI chnages. Changes in a CNIC, bnx2fc and bnx2i modules due to the new HSI. Signed-off-by:

Moved the HSI dependent slow path code to a separate file. Currently it contains the implementation of MACs, Rx mode, multicast addresses, indirection table, fast path queue and function configuration code. Signed-off-by:

While doing some backporting I noticed that vmxnet3 had a variable that was set but never used. Get rid of it, and stop the compiler from griping Signed-off-by:

l2tp_ip_sendmsg() in non connected mode incorrectly calls sk_setup_caps(). Subsequent send() calls send data to wrong destination. We can also avoid changing dst refcount in connected mode, using appropriate rcu locking. Once output route lookups can also be done under rcu, sendto() calls wont change dst refcounts too.

The network stack provides the function, skb_clone_tx_timestamp(). Ethernet MAC drivers can call this via the transmit time stamping hook, skb_tx_timestamp(). This commit exports the clone function so that drivers using it can be compiled as modules. Signed-off-by:

SNMP mibs use two percpu arrays, one used in BH context, another in USER context. With increasing number of cpus in machines, and fact that ipv6 uses per network device ipstats_mib, this is consuming a lot of memory if many network devices are registered. commit be281e55 (ipv6: reduce per device ICMP mib sizes) shrinked percpu needs for ipv6, but we can reduce memory use a bit more. With recent percpu infrastructure (irqsafe_cpu_inc() ...), we no longer need this BH/USER separation since we can update counters in a single x86 instruction, regardless of the BH/USER context. Other arches than x86 might need to disable irq in their irqsafe_cpu_inc() implementation : If this happens to be a problem, we can make SNMP_ARRAY_SZ arch dependent, but a previous poll ( https://lkml.org/lkml/2011/3/17/174 ) to arch maintainers did not raise strong opposition. Only on 32bit arches, we need to disable BH for 64bit counters updates done from USER context (currently used for IP MIB) This also reduces vmlinux size : 1) x86_64 build $ size vmlinux.before vmlinux.after text data bss dec hex filename 7853650 1293772 1896448 11043870 a8841e vmlinux.before 7850578 1293772 1896448 11040798 a8781e vmlinux.after 2) i386 build $ size vmlinux.before vmlinux.afterpatch text data bss dec hex filename 6039335 635076 3670016 10344427 9dd7eb vmlinux.before 6037342 635076 3670016 10342434 9dd022 vmlinux.afterpatch Signed-off-by:

1) the setting of NETIF_F_VLAN_CHALLENGED in bond_del_vlan() is useless since commit b2a103e6 because bond_fix_features() now sets NETIF_F_VLAN_CHALLENGED whenever the last slave is being removed. 2) the code never triggers anyway as vlan_list is never empty since ad1afb00. Signed-off-by:

There's no need for the guest to validate the checksum if it have been validated by host nics. So this patch introduces a new flag - VIRTIO_NET_HDR_F_DATA_VALID which is used to bypass the checksum examing in guest. The backend (tap/macvtap) may set this flag when met skbs with CHECKSUM_UNNECESSARY to save cpu utilization. No feature negotiation is needed as old driver just ignore this flag. Iperf shows 12%-30% performance improvement for UDP traffic. For TCP, when gro is on no difference as it produces skb with partial checksum. But when gro is disabled, 20% or even higher improvement could be measured by netperf. Signed-off-by:
