X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=275782311ca05f879a366691ceaba4e8ed643fec;p=dpdk.git

net/axgbe: fix EEPROM string comparison

drivers/net/axgbe/axgbe_phy_impl.c:576:6: error:
‘__builtin_memcmp_eq’ reading 16 bytes from a region of size 9
[-Werror=stringop-overflow=]
  if (memcmp(&sfp_eeprom->base[AXGBE_SFP_BASE_VENDOR_NAME],
      ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      AXGBE_BEL_FUSE_VENDOR, AXGBE_SFP_BASE_VENDOR_NAME_LEN))

Fixes: a5c7273771e8 ("net/axgbe: add phy programming APIs")
