Ande, Venkat Kumar ; stable@dpdk.org Subject: [PATCH v2 07/25] net/axgbe: enable PLL control for fixed PHY modes= only PLL control setting(RRC) is needed only in fixed PHY configuration to fix t= he peer-peer issues. Without the PLL control setting, the link up takes lon= ger time in a fixed phy configuration. Without the fix the user will not get the link come UP. Driver implements SW RRC for Autoneg On configuration, hence PLL control se= tting (RRC) is not needed for AN On configuration, and can be skipped. Also, PLL re-initialization is not needed for PHY Power Off and RRC command= s. Otherwise, they lead to mailbox errors. Added the changes accordingly.
