NET: Fix system hanging if NET device is not installed 2013-06-19T12:32:44+00:00 Jim Lin jilin@nvidia.com 2013-05-17T09:41:03+00:00 7315cfd9e1922ee1c3c5f016e5a3b16199122172 If we try to boot from NET device, NetInitLoop in net.c will be invoked. If NET device is not installed, eth_get_dev() function will return eth_current value, which is NULL. When NetInitLoop is called, "eth_get_dev->enetaddr" will access restricted memory area and therefore cause hanging. This issue is found on Tegra30 Cardhu platform after adding CONFIG_CMD_NET and CONFIG_CMD_DHCP in config header file.

This makes sense for most operations where the network in not known to be needed soon after the operation is complete. In the case of netconsole, it will use the network for every interaction with the shell or every printf. This means that the network is being reinitialized very often. On many devices, this intialization is very slow. This patch checks for consecutive netconsole actions and leaves the ethernet hardware initialized between them. It will still behave the same old way for all other network operations and any time another network operation happens between netconsole operations.
