pr_input is currently called in softint. Some pr_input such as ICMP, ICMPv6
and CARP can add/delete/update IP addresses and routing table entries. For
example, icmp6_redirect_input updates an a routing table entry and
nd6_ra_input may delete an IP address.
Basically such operations shouldn't be done in softint. That aside, we have
a reason to avoid the situation; psz/psref waits cannot be used in softint,
however they are required to work in such pr_input in the MP-safe world.
The change implements the workqueue pr_input framework called wqinput which
provides a means to defer pr_input of a protocol to workqueue easily.
Currently icmp_input, icmp6_input, carp_proto_input and carp6_proto_input
are deferred to workqueue by the framework.
Proposed and discussed on tech-kern and tech-net
These functions are described in the body of the man page but not
mentioned in the NAME section. Without an entry in the NAME section
apropos(1) doesn't get this man page in the results when queried for
one of those functions.
ok from christos.
introducing since release of software to be recognised. This should hopefully
allow the builds to progress a littles further on systems such as the POWER8
which features a little endian 64-bit PowerPC CPU identified as ppc64le.
mii_{read|write}reg. This function is called twie.
To identify PHY type, correct read/write function should be selected. To
select correct read/write function, PCI ID or MAC type are required without
accessing PHY registers.
On the first call of this function, PHY ID is not known yet. Check PCI ID or
MAC type. The list of the PCI ID may not be perfect, so the result might be
incorrect.
In the second call, PHY OUI and model are used to identify PHY type. It might
not be perfpect because of the lack of compared entry, but it would be better
than the first call.
If the detected new result and previous assumption is different, diagnous
message will be printed.
This is not IGP but BM. Add new case to identify PHY type correctly on this
device. Fixes PR#51924 reported byJarle Greipsland.
This change fix only for 0x10f5. Need more work to be the best.
