The following commits added support for printing the real address-
65875073eddd ("net: use %px to print skb address in trace_netif_receive_skb")
70713dddf3d2 ("net_sched: introduce tracepoint trace_qdisc_enqueue()")
851f36e40962 ("net_sched: use %px to print skb address in trace_qdisc_dequeue()")
However, tracing the packet traversal shows a mix of hashes and real
addresses. Pasting a sample trace for reference-
ping-14249 [002] ..... 3424.046612: netif_rx_entry: dev=lo napi_id=0x3 queue_mapping=0
skbaddr=00000000dcbed83e vlan_tagged=0 vlan_proto=0x0000 vlan_tci=0x0000 protocol=0x0800
ip_summed=0 hash=0x00000000 l4_hash=0 len=84 data_len=0 truesize=768 mac_header_valid=1
mac_header=-14 nr_frags=0 gso_size=0 gso_type=0x0
ping-14249 [002] ..... 3424.046615: netif_rx: dev=lo skbaddr=ffffff888e5d1000 len=84
Switch the trace print formats to %p for all the events to have a
consistent format of printing the hashed addresses in all cases.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
