Also, the offset 12 of those +ables are in the range 0x64 to 0x68. The existing sfp code assumes the +above properties. However, the Ethernet code compliance code standard +for passive cabling, suggests offset 3 is “0x0†and other offsets +4 and 5 - none of the standards are applicable. + +The 5 metre and 7 metre molex cables have valid data at offset 3 and 6, +also a value 0x78 at offset 12. So, add support to identify molex cables +and also extend the macro XGBE_SFP_BASE_BR_10GBE range to 0x78. +Change-Id: I72617bdb1d1da16f5645d9d71671e01a2d7350f6 +Signed-off-by: rgaridap <Ramesh.Garidapuri@amd.com> + +Raju Rangoju <Raju.Rangoju@amd.com> + +Change-Id: Ice85428db2c6a78f4006dc618facfb6d12c27376 +Signed-off-by: rgaridap <Ramesh.Garidapuri@amd.com> +--- + drivers/net/ethernet/amd/xgbe/xgbe-phy-v2.c | 10 +++++----- + 1 file changed, 5 insertions(+), 5 deletions(-) + +diff --git a/drivers/net/ethernet/amd/xgbe/xgbe-phy-v2.c b/drivers/net/ethernet/amd/xgbe/xgbe-phy-v2.c +index 22b2202a6d0f..278e0509cd19 100644 +--- a/drivers/net/ethernet/amd/xgbe/xgbe-phy-v2.c ++++ b/drivers/net/ethernet/amd/xgbe/xgbe-phy-v2.c +@@ -239,7 +239,7 @@ enum xgbe_sfp_speed { + #define XGBE_SFP_BASE_BR_1GBE_MIN 0x0a + #define XGBE_SFP_BASE_BR_1GBE_MAX 0x0d + #define XGBE_SFP_BASE_BR_10GBE_MIN 0x64 +-#define XGBE_SFP_BASE_BR_10GBE_MAX 0x68 ++#define XGBE_SFP_BASE_BR_10GBE_MAX 0x78 + + #define XGBE_SFP_BASE_CU_CABLE_LEN 18 + +@@ -1173,7 +1173,10 @@ static void xgbe_phy_sfp_parse_eeprom(struct xgbe_prv_data *pdata) + } + + /* Determine the type of SFP */ +- if (sfp_base[XGBE_SFP_BASE_10GBE_CC] & XGBE_SFP_BASE_10GBE_CC_SR) ++ if ((phy_data->sfp_cable == XGBE_SFP_CABLE_PASSIVE) && ++ xgbe_phy_sfp_bit_rate(sfp_eeprom, XGBE_SFP_SPEED_10000)) ++ phy_data->sfp_base = XGBE_SFP_BASE_10000_CR; ++ else if (sfp_base[XGBE_SFP_BASE_10GBE_CC] & XGBE_SFP_BASE_10GBE_CC_SR) + phy_data->sfp_base = XGBE_SFP_BASE_10000_SR; + else if (sfp_base[XGBE_SFP_BASE_10GBE_CC] & XGBE_SFP_BASE_10GBE_CC_LR) + phy_data->sfp_base = XGBE_SFP_BASE_10000_LR; +@@ -1189,9 +1192,6 @@ static void xgbe_phy_sfp_parse_eeprom(struct xgbe_prv_data *pdata) + phy_data->sfp_base = XGBE_SFP_BASE_1000_CX; + else if (sfp_base[XGBE_SFP_BASE_1GBE_CC] & XGBE_SFP_BASE_1GBE_CC_T) + phy_data->sfp_base = XGBE_SFP_BASE_1000_T; +- else if ((phy_data->sfp_cable == XGBE_SFP_CABLE_PASSIVE) && +- xgbe_phy_sfp_bit_rate(sfp_eeprom, XGBE_SFP_SPEED_10000)) +- phy_data->sfp_base = XGBE_SFP_BASE_10000_CR; + + switch (phy_data->sfp_base) { + case XGBE_SFP_BASE_1000_T: +-- +2.37.3 + |
