With current bnx2x firmware 6.2.9, iSCSI is not supported in DCB network, so we need to disable it. Add cnic command to disconnect iSCSI connections and prevent future connections when DCBX negotiation succeeds. Signed-off-by:

On-stack initialization via assignment of flow structures are expensive because GCC emits a memset() to clear the entire structure out no matter what. Add a helper for ipv4 output flow key setup which we can use to avoid the memset. Signed-off-by: -

The IRQF_SAMPLE_RANDOM flag is marked as deprecated and will be removed. Every input point to the kernel's entropy pool have to better document the type of entropy source it is. drivers/char/random.c now implements a set of interfaces that can be used for devices to collect enviromental noise. IRQF_SAMPLE_RANDOM will be replaced with these add_*_randomness exported functions. Network drivers are not a good source of entropy. They use as a source of entropy essentially a remote host. Which means that the source of entropy can be potentially controlled by an attacker. Also, with heavy workloads the entropy decreases due to less hardware interrupts happening thanks to irq mitigation and NAPI. If a system relies in its network interface as a entropy source it has a false sense of security. Systems that don't have devices whose drivers are good sources of entropy, should either use a hardware random number generator or feed the kernel's entropy pool from userspace using other sources of entropy such as EGD, video_entropyd, timer_entropyd and audio-entropyd.

Current enic code only supports ASSOCIATE and DISASSOCIATE port profile operations. This patch adds enic support for port profile PORT_REQUEST_PREASSOCIATE_RR operation. The VIC adapter (8021qbh) is capable of handling port profile requests done in two steps namely PREASSOCIATE_RR and ASSOCIATE today. The motivation to support PREASSOCIATE_RR comes mainly from its use as an optimization during VM migration ie, to do resource reservation on destination host before resources on source host are released. PREASSOCIATE_RR is a VDP operation and according to the latest at IEEE, 8021qbh will also need to support VDP commands. In addition to handling the new PORT_REQUEST_PREASSOCIATE_RR operation this patch also does the below: - Introduces handlers for PORT_REQUEST operations - Moves most of the port profile handling code to new files enic_pp.[ch] - Uses new fw devcmds for port profile operations Signed-off-by:

This patch adds wrapper routines to new port profile related fw devcmds and removes the old ones Signed-off-by:
-
Roopa Prabhu authored
This patch introduces new fw devcmds for port profile handling. These new commands are similar to the current fw commands for port profile handling. The only difference being that the new commands split the existing port profile handling devcmds into multiple fw commands, giving the driver finer control over port profile operations.

Like DCCP and other similar pieces of code, there are mechanisms here to try allocating smaller hash tables if the allocation fails. So pass in __GFP_NOWARN like the others do instead of emitting a scary message. Reported-by:

Commits 01a16b21 (netlink: kill eff_cap from struct netlink_skb_parms) and c53fa1ed (netlink: kill loginuid/sessionid/sid members from struct netlink_skb_parms) removed some members from struct netlink_skb_parms that depend on the current context, all netlink users are now required to do synchronous message processing. connector however queues received messages and processes them in a work queue, which is not valid anymore. This patch converts connector to do synchronous message processing by invoking the registered callback handler directly from the netlink receive function. In order to avoid invoking the callback with connector locks held, a reference count is added to struct cn_callback_entry, the reference is taken when finding a matching callback entry on the device's queue_list and released after the callback handler has been invoked.

Don't flap VCs when carrier state changes; higher-level protocols can detect loss of connectivity and act accordingly. This is more consistent with how other network interfaces work. We no longer use release_vccs() so we can delete it. release_vccs() was duplicated from net/atm/common.c; make the corresponding function exported, since other code duplicates it and could leverage it if it were public.

Omit pkt_hdr preamble when dumping transmitted packet as hex-dump; we can pull this up because the frame has already been sent, and dumping it is the last thing we do with it before freeing it.

According to Thomas, the former is the correct direct conversion, but it does look like both should work (arch/powerpc/sysdev/qe_lib/qe_ic.c seems to initialize both to the same thing), and the chip data in some ways is the more logical. Somebody should really decide on one of the other. This merge picks irq_desc_get_handler_data() as the straightforward pure conversion to new names, as per Thomas.
