Modified files:
sys/dev/em if_em.c
Log:
Allocate receive and transmit data structures during attach() and free them
during detach() similar to other NIC drivers rather than allocating them
during init() and freeing them during stop():
- Move creation of tx bus_dma tag amd maps and tx_buffer_area from
em_setup_transmit_structures() to em_allocate_transmit_structures().
- Call em_allocate_xxx_structures() in em_attach().
- Only call em_free_xxx_structures() in em_detach().
- Change em_setup_xxx_structures() to free any existing tx or rx buffers
and in the case of rx repopulate the ring with newer buffers.
