2020-04-23staging: vt6656: Fix calling conditions of vnt_set_bss_modeMalcolm Priestley
vnt_set_bss_mode needs to be called on all changes to BSS_CHANGED_BASIC_RATES, BSS_CHANGED_ERP_PREAMBLE and BSS_CHANGED_ERP_SLOT Remove all other calls and vnt_update_ifs which is called in vnt_set_bss_mode. Fixes an issue that preamble mode is not being updated correctly. Fixes: c12603576e06 ("staging: vt6656: Only call vnt_set_bss_mode on basic rates change.")

2020-04-23staging: vt6656: Fix pairwise key entry save.Malcolm Priestley
The problem is that the group key was saved as VNT_KEY_DEFAULTKEY was over written by the VNT_KEY_GROUP_ADDRESS index. mac80211 could not clear the mac_addr in the default key. The VNT_KEY_DEFAULTKEY is not necesscary so remove it and set as VNT_KEY_GROUP_ADDRESS. mac80211 can clear any key using vnt_mac_disable_keyentry.

2020-03-17staging: vt6656: Use BIT_ULL() macro instead of bit shift operationOscar Carter
Replace the bit left shift operation with the BIT_ULL() macro and remove the unnecessary mask off operation against the bit_nr variable. This mask is only there for legacy reasons. Originally it was 31 (0x1f) and the bit_nr variable spread across an mc_filter array with two u32 elements. Now, this mask is not needed because its value is 0x3f and the mc_filter variable is an u64 type. In this situation, the 26 bit right shift operation against the value returned by the ether_crc function set the bit_nr variable to the following value: bit 31 to bit 6 -> All 0 (due to the bit shift operation happens over an unsigned type). bit 5 to bit 0 -> The 6 msb bits of the value returned by the ether_crc function. The purpose of the 0x3f mask against the bit_nr variable is to reset (set to 0) the 26 msb bits (bit 31 to bit 6), but these bits are yet 0. So, the mask off operation is now unnecessary.
