Forwarding Engines
Each I/O module family has it's own forwarding engine. There are three Forwarding Engines; M1,F1,F2. I believe that the M2 modules basically have multiple M1 Forwarding Engines.
I/O Modules
Line card naming convention
Example N7K-M132XP-12
N7K - Nexus 7000 series line card
M1 - the forwarding engine
32 - number of ports
X - each port is capable of 10G
P - port type (P is SFP+, 2 is X2)
1 - first generation card
2 - 2 fabrics for max bandwidth
L - XL option
M Family
This family of line cards provides L2/L3/L4 with large forwarding tables and a rich feature set
M1
The M1 series line cards provide both L2 and L3 flexibility with service richness. These line cards are available with a few different port densities. All modules in this family have an integrated L2/L3 forwarding engine. M1 modules can provide proxy functions for F series modules.
The 10G cards have a maximum bandwidth per slot of 80. The 1G line cards have a maximum bandwidth of 46G per slot.

M2
The M2 series provides higher port bandwidth than the M1 series. The M2's support 10G, 40G and 100G line speeds.
F Family
The F family of line cards provides increased bandwidth at the expense of less features. Features like OTV, LISP, etc are only supported on the M series of l/O modules
F1
F1 modules provide high port density but are L2 only. Maximum bandwidth per slot of 230G. Also capable of FCoE. Must be used with another family I/O module for L3.
F2
These modules must run in an 'F2-only' VDC. Maximum bandwidth per slot of 480G. The main advantage of these modules is 48 ports of 10G are provided in a non-blocking fashion. Supports L3.
