- Tx processing is moved from the irq handler to NAPI poll - link events and obscure event processing is moved to its proper work queue Locking rules undergo some changes through the driver. - the driver offers the usual lock-free Tx path - besides the IRQ handler, the link event task schedules the napi handler. The driver thus adds some internal locking to prevent a loop when both must be disabled. - the reset task keeps being scheduled from the Tx watchdog handler, thus with implicit Tx queue disabling. It does not need to care about irq, only napi softirq and competing task. - it is not worth to add a dedicated lock between {g, s}et_wol and rhine_shutdown. It should not hurt no narrow it down a bit though. - rhine_reset_task must keep its huge spin_lock_bh protected section due to : - races for the CAM registers (see rhine_vlan_rx_{add, kill}_vid) - implicit use of napi_enable (see init_registers) - use of the same lock for stats read / update exclusion between napi rx processing and rhine_get_stats - rhine_resume requires a softirq disabled section for the same reason as rhine_reset_task - {free, request}_irq have been replaced with IntrEnable actions in rhine_{suspend, resume}. It is hidden behind init_registers for the latter. Signed-off-by:

Linus Torvalds authored
We're doing some odd things there, which already messes up various users (see the net/socket.c code that this removes), and it was going to add yet more crud to the block layer because of the incorrect error code translation. ENOIOCTLCMD is not an error return that should be returned to user mode from the "ioctl()" system call, but it should *not* be translated as EINVAL ("Invalid argument"). It should be translated as ENOTTY ("Inappropriate ioctl for device"). That EINVAL confusion has apparently so permeated some code that the block layer actually checks for it, which is sad. We continue to do so for now, but add a big comment about how wrong that is, and we should remove it entirely eventually. In the meantime, this tries to keep the changes localized to just the EINVAL -> ENOTTY fix, and removing code that makes it harder to do the right thing. Signed-off-by:

nr_frags can be 8 bits since 256 is plenty of fragments. This allows it to be packed with tx_flags. Also by moving ip6_frag_id and dataref (both 4 bytes) next to each other we can avoid a hole between ip6_frag_id and frag_list on 64 bit systems. Signed-off-by:

This patch splits the red_parms structure into two components. One holding the RED 'constant' parameters, and one containing the variables. This permits a size reduction of GRED qdisc, and is a preliminary step to add an optional RED unit to SFQ. SFQRED will have a single red_parms structure shared by all flows, and a private red_vars per flow. Signed-off-by:

SFQ as implemented in Linux is very limited, with at most 127 flows and limit of 127 packets. [ So if 127 flows are active, we have one packet per flow ] This patch brings to SFQ following features to cope with modern needs. - Ability to specify a smaller per flow limit of inflight packets. (default value being at 127 packets) - Ability to have up to 65408 active flows (instead of 127) - Ability to have head drops instead of tail drops (to drop old packets from a flow) Example of use : No more than 20 packets per flow, max 8000 flows, max 20000 packets in SFQ qdisc, hash table of 65536 slots. tc qdisc add ... sfq \ flows 8000 \ depth 20 \ headdrop \ limit 20000 \ divisor 65536 Ram usage : 2 bytes per hash table entry (instead of previous 1 byte/entry) 32 bytes per flow on 64bit arches, instead of 384 for QFQ, so much better cache hit ratio.

When a bnx2x device encounters parity errors, it will not respond to all SPQ messages. As a result, the shutdown sequence before reset can take a long time as the ulp drivers (bnx2i/bnx2fc) have to wait for timeout of all such messages. To improve this scenario, when bnx2x returns error on the SPQ, we'll send an immediate response to the ulp drivers to avoid such lengthy timeouts. Adjust the return code of relevant functions to return error only if the message cannot be sent on the SPQ so that we'll generate an error completion to the ulp drivers. Signed-off-by:
