Register 104 (Receive Frame Count for Jabber Error Frames)
This register maintains the number of giant frames received with length (including CRC) greater than 1,518 bytes (1,522 bytes for VLAN tagged) and with CRC error. If Jumbo Frame mode is enabled, then frames of length greater than 9,018 bytes (9,022 for VLAN tagged) are considered as giant frames.

WARNING: The C register and register group struct declarations are provided for convenience and illustrative purposes. They should, however, be used with caution as the C language standard provides no guarantees about the alignment or atomicity of device memory accesses. The recommended practice for writing hardware drivers is to use the SoCAL access macros and alt_read_word() and alt_write_word() functions.
