[dpdk-dev] [PATCH v2 14/20] net/ixgbe/base: initialize data field in struct buffer

[Guinan Sun]

While sending request using ixgbe_hic_unlocked() the data field in
buffer struct is not used. It is set when the struct is overwritten by
FW to deliver the response. To not pass random data to FW the whole
structure should be zeroed before use.
