vmxnet3: iPXE compatibility fixes
iPXE vmxnet3 driver makes a few assumptions regarding device operation
that were missed during testing with Linux and Windows drivers.
This patch adds following logic:
1. Additional GET commands processing added
2. Max number of RX chunks should be set to 1 when driver passes 0
via corresponding shared memory field
3. Enforecement for max chunks number added
