The main reason is that QEMU is using BOOTP protocol which is sending DHCP Offer to a broadcast address that's why it can't be disabled. DHCP protocol has no issue because it returns directly to client MAC address. Both of these options are described in RFC951 (https://datatracker.ietf.org/doc/html/rfc951#section-4) Signed-off-by: Michal Simek Reviewed-by: Ramon Fried Link: https://lore.kernel.org/r/fc5f5e2aeca77847ed4ca6a263890375ab9f5163.1642162545.git.michal.simek@xilinx.com --- diff --git a/drivers/net/zynq_gem.c b/drivers/net/zynq_gem.c index b751d28e61..2c27ffd770 100644 --- a/drivers/net/zynq_gem.c +++ b/drivers/net/zynq_gem.c @@ -62,7 +62,6 @@ #define ZYNQ_GEM_NWCFG_SPEED100 0x00000001 /* 100 Mbps operation */ #define ZYNQ_GEM_NWCFG_SPEED1000 0x00000400 /* 1Gbps operation */ #define ZYNQ_GEM_NWCFG_FDEN 0x00000002 /* Full Duplex mode */ -#define ZYNQ_GEM_NWCFG_NO_BRDC BIT(5) /* No broadcast */ #define ZYNQ_GEM_NWCFG_FSREM 0x00020000 /* FCS removal */ #define ZYNQ_GEM_NWCFG_SGMII_ENBL 0x08000000 /* SGMII Enable */ #define ZYNQ_GEM_NWCFG_PCS_SEL 0x00000800 /* PCS select */ @@ -80,7 +79,6 @@ #define ZYNQ_GEM_NWCFG_INIT (ZYNQ_GEM_DBUS_WIDTH | \ ZYNQ_GEM_NWCFG_FDEN | \ - ZYNQ_GEM_NWCFG_NO_BRDC | \ ZYNQ_GEM_NWCFG_FSREM | \ ZYNQ_GEM_NWCFG_MDCCLKDIV)
