be2net: fix sleeping while atomic bugs in be_ndo_bridge_getlink

[ Upstream commit 1a82d19ca2d6835904ee71e2d40fd331098f94a0 ]

Partially revert commit b71724147e73 ("be2net: replace polling with
sleeping in the FW completion path") w.r.t mcc mutex it introduces and the
use of usleep_range. The be2net be_ndo_bridge_getlink() callback is
called with rcu_read_lock, so this code has been broken for a long time.
Both the mutex_lock and the usleep_range can cause the issue Ian Kumlien
reported[1]. The call path is:
be_ndo_bridge_getlink -> be_cmd_get_hsw_config -> be_mcc_notify_wait ->
be_mcc_wait_compl -> usleep_range()

Merge tag 'net-next-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core
----

- Support TCPv6 segmentation offload with super-segments larger than
64k bytes using the IPv6 Jumbogram extension header (AKA BIG TCP).

- Generalize skb freeing deferral to per-cpu lists, instead of
per-socket lists.

- Add a netdev statistic for packets dropped due to L2 address
mismatch (rx_otherhost_dropped).

- Continue work annotating skb drop reasons.

- Accept alternative netdev names (ALT_IFNAME) in more netlink
requests.

- Add VLAN support for AF_PACKET SOCK_RAW GSO.

- Allow receiving skb mark from the socket as a cmsg.

- Enable memcg accounting for veth queues, sysctl tables and IPv6.

BPF
---

- Add libbpf support for User Statically-Defined Tracing (USDTs).

- Speed up symbol resolution for kprobes multi-link attachments.

- Support storing typed pointers to referenced and unreferenced
objects in BPF maps.

- Add support for BPF link iterator.

- Introduce access to remote CPU map elements in BPF per-cpu map.

- Allow middle-of-the-road settings for the
kernel.unprivileged_bpf_disabled sysctl.

- Implement basic types of dynamic pointers e.g. to allow for
dynamically sized ringbuf reservations without extra memory copies.

Protocols
---------

- Retire port only listening_hash table, add a second bind table
hashed by port and address. Avoid linear list walk when binding to
very popular ports (e.g. 443).

- Add bridge FDB bulk flush filtering support allowing user space to
remove all FDB entries matching a condition.

- Introduce accept_unsolicited_na sysctl for IPv6 to implement
router-side changes for RFC9131.

- Support for MPTCP path manager in user space.

- Add MPTCP support for fallback to regular TCP for connections that
have never connected additional subflows or transmitted
out-of-sequence data (partial support for RFC8684 fallback).

- Avoid races in MPTCP-level window tracking, stabilize and improve
throughput.

- Support lockless operation of GRE tunnels with seq numbers enabled.

- WiFi support for host based BSS color collision detection.

- Add support for SO_TXTIME/SCM_TXTIME on CAN sockets.

- Support transmission w/o flow control in CAN ISOTP (ISO 15765-2).

- Support zero-copy Tx with TLS 1.2 crypto offload (sendfile).

- Allow matching on the number of VLAN tags via tc-flower.

- Add tracepoint for tcp_set_ca_state().

Driver API
----------

- Improve error reporting from classifier and action offload.

- Add support for listing line cards in switches (devlink).

- Add helpers for reporting page pool statistics with ethtool -S.

- Add support for reading clock cycles when using PTP virtual clocks,
instead of having the driver convert to time before reporting. This
makes it possible to report time from different vclocks.

- Support configuring low-latency Tx descriptor push via ethtool.

- Separate Clause 22 and Clause 45 MDIO accesses more explicitly.

- Ethernet:
- Marvell's Octeon NIC PCI Endpoint support (octeon_ep)

Merge branch 'remove-NAPI_POLL_WEIGHT-copies'

Merge branch 'remove-NAPI_POLL_WEIGHT-copies'

Jakub Kicinski says:

====================
remove copies of the NAPI_POLL_WEIGHT define

netif_napi_add() takes weight as the last argument. The value of
that parameter is hard to come up with and depends on many factors,
so driver authors are encouraged to use NAPI_POLL_WEIGHT.

We should probably move weight to an "advanced" version of the API
(__netif_napi_add()?) and simplify the life of most driver authors.

In preparation for such API changes this series removes local
defines equivalent to NAPI_POLL_WEIGHT from drivers, so that a simple
coccinelle / spatch script does not get thrown off by them.

v2:
- drop staging bits (patch 2)
- fix subject (patch 8)
- add qeth change (patch 15)
