net: phy: introduce a quirk PHY_FLAG_BROKEN_RESET
Current driver always performs a phy soft reset when connecting the phy device, but soft reset is not always supported by a phy device, so introduce a quirk PHY_FLAG_BROKEN_RESET to let such a phy device to skip soft reset. This commit uses 'flags' of phy device structure to store the quirk. Signed-off-by: Shaohui Xie <Shaohui.Xie@nxp.com> Acked-by: Joe Hershberger <joe.hershberger@ni.com>
