[dpdk-dev] pci: fix build on FreeBSD
Commit Message
Build log:
lib/librte_eal/bsdapp/eal/eal_pci.c:462:9: error:
incompatible integer to pointer conversion passing 'u_int32_t'
(aka 'unsigned int') to parameter of type 'void *'
It is fixed by passing the pointer of pi.pi_data to memcpy.
By the way, it seems strange that pi_data is initialized twice:
.pi_data = *(u_int32_t *)buf
memcpy(&pi.pi_data, buf, len);

Please, could you explain why there are 2 initializations of pi_data
in lib/librte_eal/bsdapp/eal/eal_pci.c?
