[TG3]: ethtool -d hangs PCIe systems
Resubmitting after recommendation to use GET_REG32_1() instead of GET_REG32_LOOP(..., 1). Retested. Problem remains fixed. Prevent tg3_get_regs() from reading reserved and undocumented registers at RX_CPU_BASE and TX_CPU_BASE offsets which caused hostile behavior on PCIe platforms.
