Revision df465abfe06f7dc4f33f4a96d17f096e9e8ac917 authored by Nithin Sujir on 12 June 2013, 18:08:59 UTC, committed by David S. Miller on 13 June 2013, 09:41:51 UTC
Some systems that don't need wake-on-lan may choose to power down the chip on system standby. Upon resume, the power on causes the boot code to startup and initialize the hardware. On one new platform, this is causing the device to go into a bad state due to a race between the driver and boot code, once every several hundred resumes. The same race exists on open since we come up from a power on. This patch adds a wait for boot code signature at the beginning of tg3_init_hw() which is common to both cases. If there has not been a power-off or the boot code has already completed, the signature will be present and poll_fw() returns immediately. Also return immediately if the device does not have firmware.
