virtio-net: introduce a new control to set macaddr · 7e58d5ae

由 Amos Kong 提交于 1月 21, 2013

Currently we write MAC address to pci config space byte by byte,
this means that we have an intermediate step where mac is wrong.
This patch introduced a new control command to set MAC address,
it's atomic.

VIRTIO_NET_F_CTRL_MAC_ADDR is a new feature bit for compatibility.

net: split eth_mac_addr for better error handling · fa0879e3

由 Stefan Hajnoczi 提交于 1月 21, 2013

When we set mac address, software mac address in system and hardware mac
address all need to be updated. Current eth_mac_addr() doesn't allow
callers to implement error handling nicely.

This patch split eth_mac_addr() to prepare part and real commit part,
then we can prepare first, and try to change hardware address, then do
the real commit if hardware address is set successfully.

move virtnet_send_command() above virtnet_set_mac_address() · 40cbfc37

由 Amos Kong 提交于 1月 21, 2013

We want to send vq command to set mac address in
virtnet_set_mac_address(), so do this function moving.
Fixed a little issue of coding style.

Nicolas Dichtel says:

====================
The goal of this serie is to add the support of proxy multicast, ie being able
to build a static multicast tree. In other words, it adds the support of (*,G)
mf[6]c entries.

v2: use INADDR_ANY instead of 0 for IPv4 addresses

mcast: add multicast proxy support (IPv4 and IPv6) · 660b26dc

由 Nicolas Dichtel 提交于 1月 21, 2013

This patch add the support of proxy multicast, ie being able to build a static
multicast tree. It adds the support of (*,*) and (*,G) entries.

The user should define an (*,*) entry which is not used for real forwarding.
This entry defines the upstream in iif and contains all interfaces from the
static tree in its oifs. It will be used to forward packet upstream when they
come from an interface belonging to the static tree.
Hence, the user should define (*,G) entries to build its static tree. Note that
upstream interface must be part of oifs: packets are sent to all oifs
interfaces except the input interface. This ensures to always join the whole
static tree, even if the packet is not coming from the upstream interface.

mcast: define and use MRT[6]_MAX in ip[6]_mroute_opt() · bbb923a4

由 Nicolas Dichtel 提交于 1月 21, 2013

This will ease further addition of new MRT[6]_* values and avoid to update
in6.h each time.
Note that we reduce the maximum value from 210 to 209, but 210 does not match
any known value in ip[6]_mroute_setsockopt().

Documentation: remove obsolete networking/multicast.txt file · 202dc3fc

由 Paul Gortmaker 提交于 1月 21, 2013

The original intent of this file was to list limitations in
drivers/hardware relating to multicast use, back when some
modest hardware from the early 1990s did not support things
we might take for granted today.

I was intending to delete some now-gone MCA/token ring entries
in this file, but once I opened it, I found it only contained
information on the earliest (pre-2000) linux networking drivers.

Checking the git history shows that the file hasn't been touched
since 2005.  Clearly nobody is actively consulting this file
as a meaningful reference.

Rather than add a "YES YES YES" line for all of the drivers we
currently have, lets just take advantage of the fact that nobody
is using the file to delete it.

This has the side benefit of not having to do a line-by-line
deletion of the file content as each older driver is expired.
