Subject: [PATCH]  bnx2: bnx2_alloc_rx_mem() should use kmalloc() for small
 allocations

Hi all

# grep bnx2 /proc/vmallocinfo
0xf8218000-0xf821a000    8192 bnx2_alloc_rx_mem+0x33/0x310 pages=1 vmalloc
0xf821b000-0xf821d000    8192 bnx2_alloc_rx_mem+0x33/0x310 pages=1 vmalloc
0xf8220000-0xf8234000   81920 bnx2_init_board+0x104/0xae0 phys=f6000000 ioremap
0xf8240000-0xf8254000   81920 bnx2_init_board+0x104/0xae0 phys=fa000000 ioremap


Any chance bnx2_alloc_rx_mem doesnt use vmalloc() to allocate less than a page of memory ?

Thank you

Add two helper functions to allocate and free memory, using kzalloc() or vmalloc()
depending of the size of the allocation
