Integrity Check Value (ICV) is involved in WEP MPDU cryptographic encapsulation.
WEP computes the ICV over the plaintext data and appends this after the MPDU data. WEP encrypts the MPDU plaintext data and ICV using ARC4 with a seed. The ICV shall be computed and appended to the plaintext data prior to encryption, but the IV encoding step may occur in any order convenient for the implementation.
The overhead is due to encapsulation for encryption.
The maximum length of the Frame Body field can be determined from the maximum MSDU length plus any overhead from encapsulation for encryption --- from IEEE Std v2016
